In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0037] Currently, see Figures 2 to 3The elevator car frame 500 is provided with a main rail 510 and an auxiliary rail 530, and the main rail 510 is higher than the auxiliary rail 530 in terms of strength and selection, so the safety clamp 550 is generally arranged on the main rail 510 to ensure the safe stopping of the elevator, and to prevent the safety clamp 550 from deforming or even breaking the auxiliary rail 530 during the braking process, thereby improving the safety and stability of the elevator operation.

[0038] In related technologies, such as Figure 2 As shown, a set of main rails 510 are arranged in the middle position of the elevator car frame 500, and the auxiliary rails 530 can be staggered or biased to one side of the elevator car frame 500. For example, the auxiliary rails 530 can be selected in two positions S1 and S2, or two positions S1 and S3, or two positions S3 and S4, or two positions S2 and S4, so that one end of the elevator car frame 500 is suspended in the air, has poor balance, and is prone to deviation. In addition, the number of safety clamps 550 is small, resulting in poor shock absorption and stabilization ability of the elevator car frame 500.

[0039] Of course, if Figure 3 As shown, the auxiliary rail 530 can also select four positions S1, S2, S3 and S4 to form a six-rail structure elevator car frame 500 with a set of main rails 530, but there is a problem of high manufacturing cost due to the large amount of material used, and the small number of safety clamps 550 leads to safety hazards in the elevator during the braking process of the safety clamps 550.

[0040] See also Figure 1 The embodiment of the utility model provides a car frame structure 100. The car frame structure 100 is used in an elevator system. The elevator system includes a car 300, and the car frame structure 100 is used to support the car 300. The car frame structure 100 includes a support frame 10, a first car frame 30, a second car frame 50, two first main rails 70 and two second main rails 90. The first car frame 30 and the second car frame 50 are respectively arranged at both ends of the support frame 10 along the first direction, and the two first main rails 70 are respectively arranged at both ends of the support frame 10 along the second direction and respectively connect the two ends of the first car frame 30. The two second main rails 90 are respectively arranged at both ends of the support frame 10 along the second direction and respectively connect the two ends of the second car frame 50. The first main rail 70 and the second main rail 90 extend along the third direction, and the first direction, the second direction and the third direction are perpendicular.

[0041] The above-mentioned car frame structure 100 is provided with a first car frame 30 and a second car frame 50 at both ends of the support frame 10 along the first direction, and the two ends of the first car frame 30 are correspondingly connected to two first main rails 70 and extend along the third direction, and the two ends of the second car frame 50 are correspondingly connected to two second main rails 90 and extend along the third direction. This makes the elevator system formed by the car frame structure 100 and the car 300 more shock-absorbing and stable in operation, avoiding the car 300 from deflecting during the operation of the elevator system, with high safety, less material usage and low manufacturing cost.

[0042] Specifically, in one embodiment, Figure 1 As shown, the first car frame 30 and the second car frame 50 are respectively arranged at the two ends of the support frame 10 along the first direction. It can be understood that: the first car frame 30 and the second car frame 50 are placed in parallel and opposite to each other at the two end sides of the support frame 10 along the first direction, so that the first car frame 30 is placed at one end of the support frame 10 along the first direction (for example, the front end of the support frame 10 along the first direction), and the second car frame 50 is placed at the other end (for example, the rear end of the support frame 10 along the first direction), thereby ensuring that the first car frame 30 and the second car frame 50 can stably bear the weight of the car frame structure 100 itself, the weight of the car 300 placed in the middle of the car frame structure 100, and the weight of the cargo located in the car 300, thereby ensuring the safe and stable operation of the elevator system.

[0043] In one embodiment, if Figure 1 As shown, in the front part of the car frame structure 100 along the first direction, two first main rails 70 are respectively arranged at the two ends of the support frame 10 along the second direction and are respectively connected to the two ends of the first car frame 30, so that the two first main rails 70 are used to guide the front part of the car frame structure 100 to run along the third direction (for example, the up and down direction), so that the front part of the car frame structure 100 has no residual hanging position in the second direction (for example, the left and right direction), thereby improving the stability of the front part of the car frame structure 100 in the second direction.

[0044] Similarly, in one embodiment, if Figure 1 As shown, at the rear part of the car frame structure 100 along the first direction, two second main rails 90 are respectively arranged at the two ends of the support frame 10 along the second direction and are respectively connected to the two ends of the second car frame 50, so that the two second main rails 90 are used to guide the rear part of the car frame structure 100 to run along the third direction (for example, the up and down direction), so that the rear part of the car frame structure 100 has no suspended position in the second direction (for example, the left and right direction), thereby improving the stability of the rear part of the car frame structure 100 in the second direction.

[0045] In summary, if Figure 1 As shown, by providing two first main rails 70 and two second main rails 90 on the support frame 10, and connecting them through the first car frame 30 and the second car frame 50 respectively, the car frame structure 100 as a whole has no suspended positions at both ends of the first direction and both ends of the second direction, thereby improving the overall stability of the car frame structure 100 in the first direction and the second direction, not easily deviating, more stable shock absorption, and good safety.

[0046] It is understandable that Figure 1As shown, the car frame structure 100 forms a stable connection in the front, rear, left and right directions without any hanging position, and the two ends of the first car frame 30 are connected to the two first main rails 70, and the two ends of the second car frame 50 are connected to the two second main rails 90, so that the first car frame 30 and the second car frame 50 evenly share the load, that is, the first car frame 30 and the second car frame 50 evenly share the weight of the car frame structure 100 itself, the weight of the car 300 placed in the middle of the car frame structure 100, and the weight of the goods in the car 300, thereby ensuring that the operation process of the car frame structure 100 is more shock-absorbing and stable. For example, the first main rail 70 and the second main rail 90 prevent the car 300 from deviating in the front, rear, left and right directions, and the first car frame 30 and the second car frame 50 prevent the car 300 from shaking in the up and down directions, thereby improving the stability and safety of the elevator system.

[0047] The first car frame 30 and the second car frame 50 are respectively stably connected to the car 300, and have good safety.

[0048] That is, the car frame structure 100 of the present application can be applicable to a four-track elevator system. Compared with a six-track elevator system, the car frame structure 100 of the present application reduces the number of guide rails and the number of car frames, etc., thereby reducing the amount of materials used, reducing manufacturing costs, and ensuring that the elevator system has better shock-absorbing stability.

[0049] In one embodiment, the elevator system (not shown) may also be provided with two auxiliary rails (not shown), for example, the two auxiliary rails may be provided at the same time. Figure 1 The right side of the middle car frame structure 100 is used to assist the car frame structure 100 in safe operation.

[0050] Of course, the two auxiliary rails may also be arranged at other positions, as long as the safe operation of the car frame structure 100 is ensured, and no specific limitation is made here.

[0051] In one embodiment, the first main rail 70 and the second main rail 90 both adopt the GB / T22562-2008 elevator guide rail standard, so that the support frame 10 adopts a first main rail 70 and a second main rail 90 of larger size and strength to form a stable car frame structure 100. For example, the first main rail 70 and the second main rail 90 can adopt a nominal size of 10 mm in width. In addition, multiple safety clamps 150 can be used to achieve smooth braking, thereby ensuring that the elevator system is more shock-absorbing and stable during operation, and has good safety.

[0052] In one embodiment, if Figure 1As shown, the first direction, the second direction and the third direction are respectively the front-to-back direction, the left-to-right direction and the up-down direction, so as to ensure that the support frame 10, the first car frame 30, the second car frame 50, the two first main rails 70 and the two second main rails 90 form a stable structure of the car frame structure 100, thereby ensuring the stable placement of the car 300 and the stable operation of the elevator system.

[0053] Of course, the first direction, the second direction and the third direction may also be other mutually perpendicular directions, as long as the car frame structure 100 is stably arranged, and no specific limitation is made here.

[0054] In some embodiments, the two first main rails 70 are respectively connected to the first car frame 30 vertically and form a first plane, and the two second main rails 90 are respectively connected to the second car frame 50 vertically and form a second plane.

[0055] In this way, a car frame structure 100 with a stable structure is formed, which has good safety.

[0056] Specifically, in one embodiment, Figure 1 As shown, the two first main rails 70 are respectively connected vertically to the first car frame 30 and form a first plane. It can be understood that: the two first main rails 70 are respectively connected to the two ends of the first car frame 30 and extend downward along the third direction, so that the car frame structure 100 forms a frame structure that can lift the car 300 at the front end in the first direction, thereby ensuring that the car frame structure 100 can safely place the car 300 and safely transport the car 300 with good stability.

[0057] Similarly, in one embodiment, if Figure 1 As shown, the two second main rails 90 are respectively connected vertically to the second car frame 50 and form a second plane. It can be understood that: the two second main rails 90 are respectively connected to the two ends of the second car frame 50 and extend downward along the third direction, so that the car frame structure 100 forms a frame structure that can lift the car 300 at the rear end of the first direction, thereby ensuring that the car frame structure 100 can safely place the car 300 and safely transport the car 300 with good stability.

[0058] It can be understood that in one embodiment, the first plane is arranged parallel to the second plane, so that the car frame structure 100 formed by the first main rail 70, the first car frame 30, the second main rail 90 and the second car frame 50 has good balance and stability, thereby ensuring that the car 300 is stably placed in the placement space formed by the car frame structure 100, thereby ensuring the safe and stable operation of the elevator system.

[0059] In summary, the first main rail 70 is connected to the first car frame 30 correspondingly, and the second main rail 90 is connected to the second car frame 50 correspondingly, so that the car frame structure 100 forms a frame structure that can lift the car 300, thereby ensuring that the car frame structure 100 can safely place the car 300 and safely transport the car 300 with good stability.

[0060] In some embodiments, the car frame structure 100 includes a car top wheel assembly 110, which is disposed between the top of the car 300 and the first car frame 30, and / or;

[0061] The car top wheel assembly 110 is disposed between the top of the car 300 and the second car frame 50;

[0062] The car top wheel assembly 110 is used to guide the car 300 to move smoothly.

[0063] In this way, the elevator car 300 can be ensured to run smoothly and safely.

[0064] Specifically, in one embodiment, the car top wheel assembly 110 includes a car top wheel, wherein the car top wheel is a load-bearing wheel (such as Figure 1 As shown), during the operation of the elevator system, the car top wheel assembly 110 plays the role of fixing the car 300, and is used to support and guide the movement of the car 300.

[0065] It can be understood that the car top wheel assembly 110 can be made of materials with high tensile strength, high compressive strength and high wear resistance to ensure that the car top wheel assembly 110 can better withstand the weight and pressure of the elevator system during operation, while ensuring that the car top wheel assembly 110 has less wear during long-term use, so that the car top wheel assembly 110 maintains continuous good performance to ensure the smooth operation of the elevator system.

[0066] For example, in some examples, the material of the car top wheel assembly 110 includes but is not limited to cast iron, stainless steel, nylon material, and can also be other materials. As long as the smooth movement of the car 300 is ensured, no specific restrictions are made here.

[0067] In one embodiment, optionally, the car top wheel assembly 110 is arranged between the top of the car 300 and the first car frame 30, and the car top wheel assembly 110 is arranged between the top of the car 300 and the second car frame 50, that is, the car top wheel assembly 110 can be symmetrically arranged on the top of the car 300. For example, the number of car top wheel assemblies 110 can be 2, or 4 or other numbers, so that the car 300 runs smoothly during the ascent or descent, thereby ensuring the safety and comfort of the car 300.

[0068] Of course, the car top wheel assembly 110 can also be only arranged between the top of the car 300 and the first car frame 30, or only arranged between the top of the car 300 and the second car frame 50. It only needs to ensure the smooth lifting and lowering of the car 300, and no specific restrictions are made here.

[0069] In certain embodiments, the car frame structure 100 includes a connecting steel 130 that connects the car top wheel assembly 110 , the first car frame 30 , and the second car frame 50 .

[0070] In this way, the car top wheel assembly 110 , the first car frame 30 and the second car frame 50 are ensured to be stably connected, thereby improving the structural stability of the car frame structure 100 .

[0071] Specifically, in one embodiment, Figure 1 As shown, the connecting steel 130 can be multiple and spaced between the first car frame 30 and the car 300, and spaced between the second car frame 50 and the car 300, each connecting steel 130 is connected between the first car frame 30 and the second car frame 50 along a first direction (for example, the first direction is the front-to-back direction), thereby improving the connection stability between the first car frame 30, the connecting steel 130 and the second car frame 50, and further improving the structural stability of the car frame structure 100.

[0072] In one embodiment, the connection process between the connecting steel 130 and the first car frame 30 and the second car frame 50 can be a bolt fixing process or a riveting process, or a welding process, or other connection processes, as long as the structural stability of the car frame structure 100 is ensured, and no specific restrictions are made here.

[0073] In certain embodiments, the connection steel 130 includes at least one of an I-beam and a channel steel.

[0074] In this way, it is ensured that the connecting steel 130 has a good load-bearing capacity, thereby ensuring that the car frame structure 100 safely supports and transports the car 300 .

[0075] Specifically, in one embodiment, the I-beam is in the shape of an "I", and can be used to bear the longitudinal bending load in the car frame structure 100 to ensure that the car frame structure 100 can stably transport the car 300 along a third direction (for example, the third direction can be the up and down direction), thereby improving the shock absorption performance of the car frame structure 100 and having good stability.

[0076] For example, in some cases, I-beams can be used in bridges, large buildings, elevated roads, wind turbine towers, etc. to ensure the safety and stability of building materials in the longitudinal direction.

[0077] In one embodiment, the channel steel is a groove-shaped long steel strip, which can be used to bear the lateral bending load in the car frame structure 100 to ensure the stability of the car frame structure 100 in the first direction and the second direction, so that the car 300 is not easy to shake forward, backward, left and right, thereby improving the stability of the car frame structure 100, safety and reliability.

[0078] For example, in some cases, channel steel can be used in scenes such as mechanical platforms, TV towers, and transmission towers to ensure the safety and stability of building materials in the lateral direction.

[0079] In one embodiment, the connecting steel 130 includes at least one of an I-beam and a channel steel. It can be understood that the connecting steel 130 includes both an I-beam and a channel steel, or may only include an I-beam, or may only include a channel steel. It is only necessary to ensure the overall stability of the car frame structure 100, thereby ensuring the safe transportation of the car 300, and no specific restrictions are made here.

[0080] In one embodiment, if Figure 1 As shown, channel steels and I-beams can be arranged alternately. For example, in one example, the connecting steel 130 located at the left edge is a channel steel, and the connecting steel 130 to the right is an I-beam, so that the car frame structure 100 has a better ability to withstand longitudinal bending loads and a better ability to withstand lateral bending loads, thereby ensuring better stability of the car frame structure 100 and further ensuring safe operation of the elevator system.

[0081] In some embodiments, the car frame structure 100 includes a suspension member (not shown), which is movably connected to the car top wheel assembly 110 to enable the car 300 to move accordingly.

[0082] In this way, the car top wheel assembly 110 and the suspension member drive the car 300 to move, thereby ensuring the normal operation of the elevator system.

[0083] Specifically, in one embodiment, the suspension member (not shown) can form a winding cooperation with one of the car top wheel assemblies 110 from top to bottom along the third direction, and then be pulled up and down in the same manner to form a winding cooperation with the other car top wheel assembly 110, thereby traction car 300 to move smoothly during the operation of the elevator system.

[0084] It can be understood that the suspension can be moved by electric drive, so that friction is generated between the suspension and the car top wheel assembly 110, and the friction is used to guide electricity to the car 300, thereby realizing the lifting movement of the car 300, thereby ensuring the normal operation of the elevator system.

[0085] In one embodiment, the suspension member may be a steel wire rope or other objects to ensure that the suspension member can be movably connected to the car top wheel assembly 110 and enable the car 300 to move, and no specific limitation is made herein.

[0086] In some embodiments, the car frame structure 100 includes a load-bearing assembly (not shown), and the car top wheel assembly 110 is connected to the load-bearing assembly via a suspension member, and the load-bearing assembly is used to drive the car frame structure 100 to move.

[0087] In this way, the power for the operation of the car frame structure 100 is provided, thereby ensuring that the car frame structure 100 can achieve lifting movement.

[0088] Specifically, in one embodiment, a load-bearing assembly (not shown) may be disposed above the car frame structure 100, and the car frame structure 100 may be pulled by a suspension member to perform lifting activities, thereby ensuring the normal operation of the elevator system.

[0089] For example, in one example, the load-bearing assembly includes a drive motor (not shown), which can be used to drive the suspension member to move, so that friction is generated between the suspension member and the car top wheel assembly 110 to drive the car 300 to move up and down, thereby ensuring the normal operation of the elevator system.

[0090] In one embodiment, the load-bearing assembly may also be provided with a load-bearing plate (not shown) which can be used to bear the weight of the car frame structure 100 and the car 300, thereby ensuring the safe operation of the elevator system.

[0091] In some embodiments, the car frame structure 100 includes a protection assembly 150, which is disposed at an end of the first main rail 70 away from the first car frame 30, and / or;

[0092] The protection assembly 150 is disposed at one end of the second main rail 90 away from the second car frame 50;

[0093] The protection component 150 is configured such that, when the running speed of the elevator system exceeds a set value, the protection component 150 activates a braking function to stop the operation of the elevator system.

[0094] In this way, the car frame structure 100 can be protected, thereby ensuring the safe operation of the elevator system.

[0095] Specifically, in one embodiment, the protection component 150 may be a component for stopping the operation of the car frame structure 100, so that the elevator system can be stopped from operating in time when a fault occurs, thereby ensuring the safe operation of the elevator system.

[0096] In one embodiment, optionally, Figure 1As shown, the protection component 150 is arranged at one end of the first main rail 70 away from the first car frame 30, and the protection component 150 is arranged at one end of the second main rail 90 away from the second car frame 50. In the event of a fault in the elevator system, for example, the fault may be a fall, the protection component 150 can cooperate with the first main rail 70 and the second main rail 90 to stop respectively, thereby ensuring that the car frame structure 100 and the car 300 are stably braked, and then ensuring that the goods in the car 300 are safely and stably placed. At this time, the elevator system starts the protection state.

[0097] In one embodiment, the protection component 150 can also be separately arranged at one end of the first main rail 70 away from the first car frame 30, which can be used to ensure that the protection component 150 and the first main rail 70 cooperate in emergency braking in the event of a failure in the elevator system, thereby ensuring that the elevator system is safely in a protection state.

[0098] Among them, other braking devices can be arranged on the second main rail 90 to ensure that the entire car 300 is safer and smoother during the braking process, and has good practicality.

[0099] In one embodiment, the protection component 150 can also be separately arranged at one end of the second main rail 90 away from the second car frame 50, which can be used to ensure that the protection component 150 and the second main rail 90 cooperate in emergency braking in the event of a failure in the elevator system, thereby ensuring that the elevator system is safely in a protective state.

[0100] Among them, other braking devices can be arranged on the first main rail 70 to ensure that the entire car 300 is safer and smoother during the braking process, and has good practicality.

[0101] In one embodiment, the protection assembly 150 can clamp the first main rail 70 and the second main rail 90 to ensure that the elevator system is suspended, thereby protecting the elevator system and improving safety.

[0102] In other embodiments, the protection component 150 may also achieve emergency stopping of the elevator system by means of friction, buffering, etc., to ensure that the elevator system is safely in a protection state, which is not specifically limited here.

[0103] In one embodiment, when the running speed of the elevator system exceeds a set value, the running speed of the elevator system is too fast, indicating that a fault has occurred in the elevator system. The braking function can be activated by the protection component 150 to realize the stopping process of the elevator system, thereby suspending the operation of the elevator system and thereby ensuring the safety of the car 300.

[0104] In certain embodiments, the protection assembly 150 includes a double-link safety gear.

[0105] In this way, the protection component 150 can achieve synchronous braking to improve the stability of the elevator system.

[0106] Specifically, in one embodiment, Figure 1 As shown, the protection component 150 includes a double-linkage safety clamp, so that the protection component 150 can synchronously clamp the two first main rails 70, and can also synchronously clamp the two second main rails 90. It can also be 2 groups of protection components 150 and synchronously clamp the two first main rails 70 and the two second main rails 90. In the event of a failure in the elevator system, it is ensured that the car frame structure 100 and the car 300 are suspended and stably placed, with good safety.

[0107] It can be understood that by arranging double-linked safety clamps on the two first main rails 70 and double-linked safety clamps on the two second main rails 90, the synchronization of the actions of the four safety clamps can be ensured to avoid inconsistency in the actions of the four safety clamps, which would cause the car 300 to tilt and deform when stopped, thereby avoiding the occurrence of safety accidents in the elevator system.

[0108] In one embodiment, the double-linked safety clamp may be provided with a wedge (not shown). When the operating speed of the elevator system exceeds a set value, the double-linked safety clamp may use a wedge or other braking element to clamp on the first main rail 70 and the second main rail 90, thereby quickly decelerating and stopping the car 300, thereby ensuring that the elevator system is safely in a protective state.

[0109] An embodiment of the utility model provides an elevator system, and the elevator system includes a car frame structure 100 of any one of the above embodiments.

[0110] The above-mentioned elevator system is provided with a first car frame 30 and a second car frame 50 at both ends of the support frame 10 along the first direction, and the two ends of the first car frame 30 are correspondingly connected to two first main rails 70 and extend along the third direction, and the two ends of the second car frame 50 are correspondingly connected to two second main rails 90 and extend along the third direction, so that the elevator system formed by the car frame structure 100 and the car 300 can be more shock-absorbing and run smoothly, avoiding the car 300 from deflecting during the operation of the elevator system, with high safety, less material usage and low manufacturing cost.

[0111] Specifically, in one embodiment, the elevator system includes but is not limited to an elevator with a traction ratio of 4 to 1 or an elevator with a small machine room.
