[0030] The technical solutions in the present application will be described clearly and exhaustively in combination with the drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B: "and / or" in the text only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent: A exists alone, A and B exist together, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0031] Hereinafter, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more features.

[0032] In the related art, the car bottom structure of the large-load freight elevator is mostly extended based on the design idea of the conventional elevator car bottom, and is processed and formed by bending plate materials or welding profiles. Since the size of the car exceeds the size of the raw material, part of the structure needs to be spliced and welded on site to realize overall forming. However, the above-mentioned car bottom structure needs to be spliced and welded on site, which increases the process complexity and time cost of on-site installation, reduces the assembly efficiency, and moreover, the size of the formed part of the assembly is too large to exceed the carrying range of the conventional transportation tool, resulting in increased transportation difficulty.

[0033] Therefore, the embodiments of the present application provide a car and an elevator, which set the car bottom structure of the car as a spliced type, which is not only convenient for transportation, but also has high assembly efficiency.

[0034] It should be noted that the elevator provided by the embodiments of the present application includes but is not limited to a large-load freight elevator. Herein, the specific type of the elevator provided by the embodiments of the present application is not limited.

[0035] The embodiments of the present application will be described in detail in combination with the drawings and specific embodiments.

[0037] As shown in the figure, the embodiment provides a car, the car has a first extension direction, a second extension direction and a third extension direction perpendicular to each other, the size of the car in the first extension direction is greater than the size of the car in the second extension direction, and the size of the car in the second extension direction is greater than the size of the car in the third extension direction. Wherein, the first extension direction can be understood as the length direction of the car, that is, the X-X axis direction in Figures 1 to 3 , Figure 1 and Figure 2 , the second extension direction can be understood as the height direction of the car, that is, the Z-Z axis direction in Figure 1 , Figure 3 , and the third extension direction can be understood as the width direction of the car, that is, the Y-Y axis direction in

[0038] Specifically, the car provided by the embodiment includes a car bottom structure 1 and a first support assembly 2; the car bottom structure 1 includes a plurality of car bottom units 11 spliced together along the first extension direction, and a first splicing joint 12 is formed between two adjacent car bottom units 11; the first support assembly 2 is connected to the bottom end of the car bottom structure 1, and the first support assembly 2 includes a plurality of support units 21 arranged at intervals along the third extension direction, each support unit 21 includes a plurality of first support pieces 211 spliced together along the first extension direction, and a second splicing joint 212 is formed between two adjacent first support pieces 211; wherein, the first splicing joint 12 and the second splicing joint 212 are staggered in the first extension direction, and the second splicing joints 212 of two adjacent support units 21 are staggered in the first extension direction.

[0039] In this way, the size of a single car bottom unit 11 and the first support piece 211 is adapted to the conventional transportation tool, and to some extent, the transportation problem caused by the oversize of the formed assembly in the related art is solved; at the same time, the modular splicing replaces the complex welding on site, simplifies the installation process, shortens the installation period, and improves the assembly efficiency.

[0040] In addition, by limiting the positions of the first splicing joint 12 and the second splicing joint 212, the defect of stress concentration when splicing the same joint is avoided, and the huge impact load of loading and unloading goods is dispersed layer by layer to different joints and support units 21 through multi-stage staggered joints, so that a single part is not damaged due to load concentration, and the carrying capacity and stability of the overall structure are improved.

[0041] It should be noted that in the specific implementation of the embodiment, the first support piece 211 described above can be an I-beam extending along the first extension direction. Here, the type of the first support piece 211 is not specifically limited.

[0042] Please continue to combine Figure 4 and Figure 5 , Figure 4 for Figure 1A local structure at the middle A is shown in an enlarged schematic view, Figure 5 As Figure 2 A first local structure of the structure shown in an enlarged schematic view. In order to further improve the impact resistance of the car bottom structure 1, in some embodiments, the car provided by the present embodiment further comprises a plurality of beam units 3, two second support assemblies 4 and two reinforcing assemblies 5; the plurality of beam units 3 are connected to the bottom ends of the plurality of support units 21, the plurality of beam units 3 are arranged in a spaced manner along the first extension direction, the plurality of beam units 3 comprise two end beam units 31 located at the ends, each beam unit 3 comprises two beams 32 arranged in a spaced manner along the first extension direction, and the two beams 32 are arranged in opposite directions; the two second support assemblies 4 are arranged in a one-to-one correspondence with the two end beam units 31, and the second support assembly 4 is arranged at the bottom end of the first support assembly 2; each second support assembly 4 is connected between the two beams 32 of the corresponding end beam unit 31, and each second support assembly 4 comprises a plurality of second support pieces 41 arranged in a spaced manner along the third extension direction; the two reinforcing assemblies 5 are arranged in a one-to-one correspondence with the two second support assemblies 4, each reinforcing assembly 5 comprises a plurality of reinforcing pieces 51 arranged in a spaced manner along the third extension direction, the plurality of reinforcing pieces 51 are arranged in a one-to-one correspondence with the plurality of second support pieces 41, the reinforcing piece 51 is connected between the corresponding first support piece 211 and the corresponding second support piece 41, and the reinforcing piece 51 extends in an inclined manner.

[0043] Among them, the beam unit 3 can quickly spread the heavy load transmitted by the first support assembly 2 to a larger force bearing surface, avoiding excessive local pressure; the two second support assemblies 4 can strengthen the weak bearing problem prone to occur at the ends due to stress concentration.

[0044] And the reinforcing assembly 5 corresponding to the second support assembly 4, the plurality of reinforcing pieces 51 are arranged in a one-to-one correspondence with the second support pieces 41 and are connected between the first support piece 211 and the second support piece 41 in an inclined state, this inclined structure naturally forms a stable triangular support stress form, improves the force transmission efficiency between the first support assembly 2 and the second support assembly 4, effectively buffers and eliminates the local stress mutation in the load transmission process, so that the impact resistance of the entire car bottom structure 1 is more suitable for the working condition of heavy cargo loading and unloading.

[0045] It should be noted that in some specific embodiments, the second support piece 41 extends along the first extension direction, and the above-mentioned second support piece 41 and reinforcing piece 51 can be a channel steel. Here, the types of second support piece 41 and reinforcing piece 51 are not specifically limited.

[0047] Among them, the two foot protection plates 6 not only can form physical protection to the end structure of the first support assembly 2, avoid collision damage to the end assembly during the loading and unloading of goods, but also can strengthen the overall structural stability of the first support assembly 2 through end closure, and reduce the deformation risk of the end due to the load.

[0048] And the inclined layout of the first end 511 of the reinforcing member 51 close to the foot protection plate 6 and the first support member 211, and the second end 512 away from the foot protection plate 6 and the second support member 41 forms a diagonal support path extending from the end of the first support assembly 2 to the internal support structure. This layout makes the external impact or end concentrated load borne by the foot protection plate 6 quickly transmitted to the base frame composed of the second support assembly 4 and the cross beam unit 3 through the reinforcing member 51, avoiding the accumulation of load at the end; at the same time, the diagonal support can enhance the connection strength of the end of the first support assembly 2 and the bottom support structure, further improving the impact resistance of the end structure and the overall load bearing reliability.

[0049] In some specific embodiments, the first end 511 of the reinforcing member 51 is a first end plate connected with the first support member 211, the second end 512 of the reinforcing member 51 is a second end plate connected with the second support member 41, the first end plate extends along the horizontal direction, the second end plate extends along the vertical direction, the first end plate and the first support member 211 are connected through screws or other threaded fasteners, and the second end plate and the second support member 41 are connected through screws or other threaded fasteners.

Specifically, the upper end of the foot protection plate 6 extends above the first support assembly 2 and is connected with the threshold assembly 7, and the lower end of the foot protection plate 6 extends below the first support assembly 2.

[0051] The sill assembly 7 is a core connecting component of the car body 8 and the landing, and the end mounting mode can build a smooth transition surface, avoid the jamming and dumping of goods due to the gap or height difference during connection, and improve the operation safety and efficiency. The car body 8 is connected to the top end of the car bottom structure 1.

[0052] In addition, the connection of the sill assembly 7 and the first support assembly 2 forms an end additional stress node, so that the end load can be directly transmitted to the support system, optimizing the load transmission path and complementing the end reinforcement structure, and at the same time realizing the end positioning and reinforcement of the car bottom structure 1, reducing the deformation risk under heavy load.

[0053] The specific structure of the sill assembly 7 can be that the sill assembly 7 includes a bracket 71 and a sill 72 connected together, and specifically, the bracket 71 and the sill 72 are welded together; the top end of the first support 211, the car bottom structure 1 and the foot guard plate 6 are connected with the bracket 71, and the sill 72 is connected to the top end of the bracket 71. In this way, the bracket 71 and the sill 72 are connected as a whole, which not only provides stable support for the sill 72 and avoids its deformation and displacement during loading and unloading of goods and elevator operation, but also simplifies the assembly process of the sill assembly 7.

[0054] In the specific embodiment of the present embodiment, the bracket 71 and the first support 211 are welded together, and the bracket 71 and the car bottom structure 1 are connected together through screws or other threaded fasteners, and the top end of the foot guard plate 6 is also connected together through screws or other threaded fasteners. Here, the connection mode between the sill assembly 7 and other structures is not specifically limited.

[0056] In this way, the load-bearing strength of the car bottom unit 11 itself is ensured, and the stable connection of the car bottom structure 1 and the first support assembly 2 is realized through the connection of the support beam 112 and the first support piece 211. Moreover, the adjacent car bottom units 11 are connected through the butt joint of the two oppositely arranged support beams 112, and are detachably connected through the fastener 9. Not only is the cumbersome on-site welding process saved, the assembly efficiency is improved, but also flexible adaptation to different size requirements is achieved, and the detachable design also provides convenience for subsequent maintenance and replacement of parts, taking into account the structural stability and use flexibility.

[0057] Specifically, the first splicing joint 12 includes a first joint section 121 and a second joint section 122, the first joint section 121 is formed between two adjacent top plates 111, and the second joint section 122 is formed between two oppositely arranged support beams 112 connected together.

[0058] Among them, the top plate 111 and the support beam 112 are welded together, and the support beam 112 and the first support piece 211 are detachably connected together through a threaded fastener such as a screw. Here, the connection mode between the top plate 111 and the support beam 112, and between the support beam 112 and the first support piece 211 is not specifically limited.

[0059] It can be understood that when the elevator appears abnormal conditions such as overspeed, the car body 8 needs to be braked on the guide rail to stop moving. Therefore, please continue to combine Figures 8 to 10 , Figure 8 for Figure 1 the structure of the local structure of the structure shown in the structure, Figure 9 for Figure 8 the structure of the local structure of the structure shown in the structure, Figure 10 for Figure 9 the local structure of C in the structure is shown in the enlarged schematic view.

[0060] The car provided by the embodiment further comprises a plurality of column units 10, a plurality of first guide rails (not shown in the figure), a plurality of second guide rails (not shown in the figure), a plurality of first safety clamps 20 and a plurality of second safety clamps 30; the plurality of column units 10 are arranged at intervals along a first extension direction, and the plurality of column units 10 are arranged one by one with the plurality of beam units 3; each column unit 10 comprises a first column 101 and a second column 102, and the first column 101 and the second column 102 are respectively located on both sides of the car bottom structure 1 along a third extension direction; the first column 101 is connected between one end of the two beams 32 of the corresponding beam unit 3, and the second column 102 is connected between the other end of the two beams 32 of the corresponding beam unit 3; the plurality of first guide rails and the plurality of second guide rails are respectively located on both sides of the car bottom structure 1 along the third extension direction, and the plurality of first guide rails and the plurality of second guide rails are arranged at intervals along the first extension direction; the plurality of first guide rails are arranged one by one with the plurality of first columns 101, and the plurality of second guide rails are arranged one by one with the plurality of second columns 102; the first guide rail is connected to the corresponding first column 101, and the second guide rail is connected to the corresponding second column 102; the plurality of first safety clamps 20 and the plurality of second safety clamps 30 are respectively located on both sides of the car bottom structure 1 along the third extension direction; the plurality of first safety clamps 20 are arranged one by one with the plurality of first guide rails, and the plurality of second safety clamps 30 are arranged one by one with the plurality of second guide rails; the first safety clamp 20 is connected to the bottom end of the corresponding first column 101, and the second safety clamp 30 is connected to the bottom end of the corresponding second column 102; the first safety clamp 20 is used to lock the corresponding first guide rail, and the second safety clamp 30 is used to lock the corresponding second guide rail; wherein the plurality of first safety clamps 20 and the plurality of second safety clamps 30 can simultaneously lock the corresponding first guide rail and the corresponding second guide rail.

[0061] The plurality of column units 10 correspond one by one to the plurality of beam units 3, and the first column 101 and the second column 102 of each column unit 10 are respectively connected to both ends of the two beams 32 of the corresponding beam unit 3; in this way, a symmetrical and stable frame structure can be constructed, which provides a reliable support foundation for the installation of the first guide rail, the second guide rail, the first safety clamp 20 and the second safety clamp 30, and the layout arranged at intervals along the first extension direction can balance and disperse the overall stress.

[0062] In addition, the first guide rail and the second guide rail are respectively connected one by one with the first column 101 and the second column 102, and are symmetrically distributed on both sides of the car bottom structure 1 along the third extension direction; in this way, not only the verticality and spacing accuracy of the guide rail installation are ensured to provide smooth guidance for the operation of the elevator, but also a cooperative stress system can be formed with the column unit 10 to enhance the frame lateral displacement resistance.

[0063] Further, the plurality of first safety clamps 20 and the plurality of second safety clamps 30 are respectively connected to the bottom ends of the corresponding first upright columns 101 and second upright columns 102, and can simultaneously clamp the corresponding first guide rails and second guide rails. This symmetrical and synchronous braking design makes the braking force evenly distributed on both sides of the car bottom structure 1, avoiding structural tilting or damage caused by uneven force during braking, and improving the safety and reliability of elevator braking in heavy load conditions.

[0064] It should be noted that in the present embodiment, only the bottom ends of the first upright columns 101 and second upright columns 102 located in the middle are provided with the first safety clamps 20 and the second safety clamps 30. For example, referring to Figure 2 , the bottom ends of the five first upright columns 101 and second upright columns 102 located in the middle are provided with the first safety clamps 20 and the second safety clamps 30.

[0065] In order to realize the simultaneous action of the plurality of first safety clamps 20 and the plurality of second safety clamps 30, the car provided in the present embodiment further comprises a lifting assembly 40 and a linkage assembly 50, the linkage assembly 50 is connected together with the lifting assembly 40; the linkage assembly 50 is connected to each first safety clamp 20 and each second safety clamp 30, so that the plurality of first safety clamps 20 and the plurality of second safety clamps 30 can simultaneously clamp the corresponding first guide rails and the corresponding second guide rails. In this way, centralized control and synchronous triggering of braking action are realized. Avoiding the braking time difference that may occur when a single safety clamp acts independently, ensuring that all first safety clamps 20 and second safety clamps 30 clamp the corresponding guide rails simultaneously when needed, making the braking force evenly distributed on both sides of the car bottom structure 1 instantaneously, effectively preventing the car body 8 from tilting, jamming or even damaging due to unbalanced braking in heavy load conditions.

[0066] Please continue to combine Figure 11 and Figure 12 , Figure 11 for Figure 10 the enlarged schematic view of the local structure at D in FIG. 8, Figure 12 for Figure 10 the enlarged schematic view of the local structure at E in FIG. 8. As shown in the figure, the first safety clamp 20 has two first lifting rods 201, and the second safety clamp 30 has two second lifting rods 301; the linkage assembly 50 includes a linkage shaft 501 and a plurality of linkage structures 502, the linkage shaft 501 is connected together with the lifting assembly 40, and each linkage structure 502 is connected between the oppositely arranged first safety clamp 20 and second safety clamp 30; wherein the lifting assembly 40 can drive the linkage shaft 501 to rotate, and then drive the first lifting rod 201 and the second lifting rod 301 to move upward through the linkage structure 502.

[0067] That is, after the pulling assembly 40 drives the linkage shaft 501 to rotate, the linkage structure 502 synchronously drives the corresponding first pulling rod 201 and second pulling rod 301 to move upward, which not only ensures that the two pulling rods of the same side safety clamp are balanced in force, but also realizes that the first safety clamp 20 and the second safety clamp 30 arranged oppositely are completely synchronized in action. In this way, the braking deviation caused by the unbalanced force or delayed action of a single pulling rod during braking is avoided, so that all safety clamps can be locked to the guide rail with consistent force and rhythm, further improving the stability and reliability of the elevator braking provided by the embodiment.

[0068] In some specific embodiments, the linkage structure 502 includes two first linkages 5021, a linkage rod 5022, a pulling shaft 5023, and two second linkages 5024; the two first linkages 5021 are connected together with the linkage shaft 501, and the two first linkages 5021 are arranged one-to-one with the two first pulling rods 201, and the end of the first linkage 5021 is connected with the corresponding first pulling rod 201; one end of the linkage rod 5022 is connected with the linkage shaft 501; the other end of the linkage rod 5022 is connected with the pulling shaft 5023; the two second linkages 5024 are connected with the pulling shaft 5023, and the two second linkages 5024 are arranged one-to-one with the second pulling rods 301, and the end of the second linkage 5024 is connected with the corresponding second pulling rod 301.

[0069] Specifically, when the pulling assembly 40 drives the linkage shaft 501 to rotate, it will synchronously drive the first linkage 5021 to rotate, and then drive the corresponding first pulling rod 201 to move upward smoothly; at the same time, the linkage shaft 501 will drive the linkage rod 5022 to pull back, so as to drive the pulling shaft 5023 to rotate, and then drive the second linkage 5024 to rotate, so as to realize the synchronous upward movement of the second pulling rod 301. The integrated transmission design of the first pulling rod 201 and the second pulling rod 301 under the same linkage structure 502 completely synchronizes the action of the first pulling rod 201 and the second pulling rod 301, and the one-to-one matching mode ensures uniform force transmission, avoids the situation that a single pulling rod is delayed or unbalanced in force, improves the response accuracy and stability of the braking system, and makes the transmission process clear and controllable, reducing the difficulty of fault diagnosis and maintenance.

[0070] The first linkage member 5021 comprises a linkage plate 510, a first reinforcing plate 520, a second reinforcing plate 530 and a guide block 540. The first reinforcing plate 520 is connected to one end of the linkage plate 510 and is welded to the linkage shaft 501. The second reinforcing plate 530 is connected to the other end of the linkage plate 510. The second reinforcing plate 530 and the linkage plate 510 enclose a guide cavity 550. The guide block 540 is arranged in the guide cavity 550 and is connected to the second reinforcing plate 530. The guide block 540 is connected to the first lifting rod 201. In order to limit the guide block 540 on the first lifting rod 201, the upper end of the guide block 540 is provided with a limiting nut 60 connected to the first lifting rod 201. In this way, the transmission connection between the linkage shaft 501 and the first lifting rod 201 is realized through the first linkage member 5021.

[0071] In order to realize the connection between the linkage shaft 501 and the linkage rod 5022, the first connecting seat 70 is arranged on the linkage shaft 501. The first connecting seat 70 comprises a connecting body 701 and a connecting rod 702. The connecting body 701 is fixedly connected to the linkage shaft 501. The connecting rod 702 is integrally formed with the connecting body 701. The end of the connecting rod 702 is provided with a protruding column 7021. One end of the linkage rod 5022 is provided with a matching hole 560 through which the protruding column 7021 passes. Through the cooperation of the protruding column 7021 and the matching hole 560, the linkage rod 5022 can be pulled back during the rotation of the linkage shaft 501.

[0072] Further, in order to realize the transmission connection between the linkage rod 5022 and the lifting shaft 5023, the second connecting seat 80 which has the same structure as the first connecting seat 70 is arranged on the lifting shaft 5023. The connection relationship between the second connecting seat 80 and the lifting shaft 5023 can be referred to the connection relationship between the first connecting seat 70 and the linkage shaft 501. The connection relationship between the second connecting seat 80 and the linkage rod 5022 can be referred to the connection relationship between the first connecting seat 70 and the linkage rod 5022. Here, no further description is given. In this way, the lifting shaft 5023 can be rotated during the pulling back of the linkage rod 5022, and the second lifting rod 301 can be lifted up under the transmission action of the second linkage member 5024.

[0073] It should be noted that the structure of the second linkage member 5024 is the same as that of the first linkage member 5021. Moreover, the connection and cooperation relationship between the second linkage member 5024 and the lifting shaft 5023 can be referred to the connection and cooperation relationship between the first linkage member 5021 and the linkage shaft 501. The connection and cooperation relationship between the second linkage member 5024 and the second lifting rod 301 can be referred to the connection and cooperation relationship between the first linkage member 5021 and the first lifting rod 201. Here, no further description is given.

[0074] Further, the first lifting rod 201 and the second lifting rod 301 can be ensured to move upward during the rotation of the linkage shaft 501 and the lifting shaft 5023. In some optional embodiments, the first linkage member 5021 has a first through hole 5025 through which the first lifting rod 201 passes, and the second linkage member 5024 has a second through hole 5026 through which the second lifting rod 301 passes; the first through hole 5025 is in clearance fit with the first lifting rod 201, and the second through hole 5026 is in clearance fit with the second lifting rod 301.

[0075] In this way, a reasonable space is reserved for the movement of the first lifting rod 201 and the second lifting rod 301. Neither the first lifting rod 201 nor the second lifting rod 301 is stuck when moving upward due to too tight fit, ensuring the smoothness of the operation process of the linkage assembly 50, nor is it difficult to butt joint due to dimensional error during assembly, improving the installation convenience. Meanwhile, the clearance fit can reduce the friction loss between the first linkage member 5021, the second linkage member 5024 and the corresponding lifting rod, prolong the service life of the components, and also can buffer slight stress deviation during braking transmission, ensuring the stability of the force transmission.

[0076] Specifically, the first through hole 5025 is arranged on the guide block 540, and the second through hole 5026 is also arranged on the corresponding structure of the second linkage member 5024.

[0077] The structure of the lifting assembly 40 can be that the lifting assembly 40 includes a steel wire rope (not shown in the figure) and a lifting member 401, the end of the steel wire rope is fixed on the lifting member 401, and the lifting member 401 is connected with the linkage shaft 501 of the linkage assembly 50. In this way, the steel wire rope of the speed limiter can drive the lifting member 401 to rotate, and then drive the linkage shaft 501 to rotate.

[0078] Please continue to combine Figure 13 and Figure 14 , Figure 13 a plane structure schematic view of a partial structure of the first safety gear or the second safety gear in the elevator provided by the embodiment of the application, Figure 14 for Figure 13A stereogram of the structure is shown. In order to improve the clamping effect of the first safety clamp 20 on the first guide rail and the clamping effect of the second safety clamp 30 on the second guide rail, in some embodiments, the first safety clamp 20 and the second safety clamp 30 each include two safety clamp units 90 stacked together in the up-down direction; the safety clamp unit 90 includes a fixed seat 91, two guide pieces 92, and a brake structure 93; the fixed seats 91 of the two safety clamp units 90 are connected together, and the fixed seat 91 at the upper end is connected together with the corresponding first stand 101 or second stand 102; the two guide pieces 92 are connected to the inner side of the fixed seat 91, the guide piece 92 has a guide surface 921 facing the other guide piece 92, the guide surface 921 extends obliquely in the up-down direction, and the top ends of the two guide surfaces 921 are close to each other; the brake structure 93 includes two sliding blocks 931, which are arranged one by one corresponding to the two guide pieces 92, the sliding block 931 is in sliding fit with the corresponding guide surface 921, and the sliding block 931 has a brake part 9311 facing the other sliding block 931; wherein the brake structures 93 of the two safety clamp units 90 can be collectively moved upward to clamp the corresponding first guide rail or the corresponding second guide rail.

[0079] In this way, the brake structures 93 of the two safety clamp units 90 collectively move upward to clamp the guide rail, which is equivalent to the superposition of double braking forces, improves the clamping force, and adapts to the braking requirements of large-load elevators. At the same time, the up-down stacked layout makes the braking force more uniform, avoiding local stress concentration leading to damage to the guide rail or the safety clamp.

[0080] In order to realize the collective upward movement of the two brake structures 93, in the present embodiment, the first safety clamp 20 and the second safety clamp 30 further include a connecting plate 100, a brake lever 110, and two connecting pieces 120; the connecting plate 100 is located above the two fixed seats 91, and the connecting plate 100 is connected with the two first pull levers 201 or the two second pull levers 301; the brake lever 110 is connected to the connecting plate 100, and the brake lever 110 extends from the upper side of the connecting plate 100 to between the two sliding blocks 931 of the safety clamp unit 90 at the lower end; the two connecting pieces 120 are arranged one by one corresponding to the two safety clamp units 90, and the two sliding blocks 931 are connected on both sides of the corresponding connecting piece 120.

[0081] Among them, the connecting plate 100 receives the driving force of the two first pull levers 201 or the two second pull levers 301 and transmits it to the brake lever 110, so that the upward force of the pull lever can accurately act on the sliding block 931 of the safety clamp unit 90 at the lower end, realizing efficient transmission of power.

[0082] And the two connecting pieces 120 correspond to the two safety clamp units 90 one by one, and connect the two sliding blocks 931 of each safety clamp unit 90 as a whole, which not only ensures that the two sliding blocks 931 in the same safety clamp unit 90 slide synchronously along the guide surface 921, avoids unilateral deviation affecting the braking effect, but also can drive the braking structure 93 of the two safety clamp units 90 to move upward synchronously through the driving of the brake lever 110, so that the double braking forces work together. In this way, the power transmission path is clear and concentrated, and the action synchronization and reliability of the braking system are improved.

[0083] In order to further improve the locking effect of the braking structure 93 on the first guide rail and the second guide rail, in some embodiments, the braking part 9311 is formed with two braking areas 9312 spaced apart in the up-down direction, and the braking area 9312 is arranged towards the other sliding block 931; wherein the braking area 9312 is formed with a plurality of closely arranged sawtooth structures 9313. The design of the two braking areas 9312 distributed in the up-down direction increases the contact area with the guide rail, so that the braking force is more uniform in the up-down direction, and avoids local wear caused by excessive force on a single area.

[0084] Secondly, the sawtooth structure 9313 can improve the friction between the braking part 9311 and the guide rail, especially when braking under heavy load, which can enhance the locking effect and prevent slipping, further ensuring the reliability of braking.

[0085] In order to improve the stability and reliability of the guide 92 installed on the fixed seat 91, in some embodiments, the fixed seat 91 includes a seat body 911, two support blocks 912 and two limiting plates 913; the seat body 911 is internally formed with a guide space 9111, the guide space 9111 has two opposite fixed walls 9112, and the two guides 92 are located between the two fixed walls 9112; the two support blocks 912 are arranged one by one corresponding to the two guides 92, the support block 912 is connected to the fixed wall 9112, and the side wall of the support block 912 is resisted by the corresponding guide 92; the two limiting plates 913 are located below the two support blocks 912, and the two limiting plates 913 are arranged one by one corresponding to the two guides 92, the limiting plate 913 is connected to the fixed wall 9112, the guide 92 has a limiting cavity 922 matched with the limiting plate 913, and the limiting plate 913 extends into the corresponding limiting cavity 922.

[0086] The guiding space 9111 provides a mounting and positioning base for the two guides 92, so that the guiding surfaces 921 of the guides 92 can maintain a preset inclination angle and relative position. The two support blocks 912 correspondingly resist the guides 92, and stably support the guides 92 from the side to avoid deviation of the guides 92 under force during braking. The two limiting plates 913 below extend into the limiting cavities 922 of the guides 92, further limiting the upward and downward displacement and shaking of the guides 92, and achieving bidirectional limiting and fixing of the guides 92. In this way, it is ensured that the guides 92 can still maintain structural stability under long-term braking force, providing reliable protection for smooth sliding and accurate braking of the sliding block 931, and also improving the overall structural strength and service life of the safety clamp unit 90.

[0087] In the specific implementation of the embodiment, the seat body 911 includes an upper support plate 9113 and a lower support plate 9114 arranged opposite in the up-down direction, and the upper support plate 9113 and the lower support plate 9114 are connected by a support connecting piece 9115. The guiding space 9111 is formed by the upper support plate 9113, the lower support plate 9114, and the support connecting piece 9115.

[0088] The support block 912 and the support connecting piece 9115 are connected together by a screw or other threaded fastener, and the limiting plate 913 and the support connecting piece 9115 are welded together. Here, the connection mode between the support block 912 and the support connecting piece 9115, and the connection mode between the limiting plate 913 and the support connecting piece 9115 are not specifically limited.

[0089] The upper support plate 9113 of the fixed seat 91 located above is connected together with the corresponding first column 101 or second column 102 by a screw or other threaded fastener.

[0090] The car provided in the embodiment further includes a guardrail assembly 130. The guardrail assembly 130 includes two guardrail units 131 connected to the two ends of the car body 8 along the third extension direction. Each guardrail unit 131 includes a plurality of guardrails 1311 spliced together along the first extension direction.

[0091] The two guardrail units 131 are arranged at the left and right ends of the car body 8, can form boundary protection, and clearly define the work safety area. The plurality of guardrails 1311 spliced together along the first extension direction can be adapted to the top ends of car bodies 8 of different lengths, ensuring full coverage of the protection range, facilitating split transportation and on-site installation, and enabling individual replacement when a local part is damaged, without affecting the overall protection function of the guardrail assembly 130.
