Description

Technical Field

[0001] The present invention relates to the technical field of construction machinery, and in particular to a rotating mechanism and construction equipment. Background Art

[0002] In the construction field, it is often necessary to transport materials or install them in specific locations. In the process of using mechanical equipment to assist in transportation, the related technology often requires the mechanical equipment to rotate the materials before transporting them. The existing mechanical equipment includes a fixed part, a rotating bearing part and a drive assembly. The body of the drive assembly is fixed to the fixed part, and the extension shaft of the drive assembly extends from the body and can rotate relative to the body. The extension shaft and the rotating bearing part are connected through a transmission structure such as a gear assembly. The setting of the transmission structure causes the structure of the mechanical equipment to be not compact, and the overall volume of the mechanical equipment is relatively large, thereby occupying a large space, which limits the use of the mechanical equipment in a smaller building environment and affects the construction efficiency. Summary of the invention

[0003] The object of the present invention is to provide a rotating mechanism and construction equipment with compact structure and small occupied space.

[0004] To achieve this object, the present invention adopts the following technical solutions:

[0005] A rotating mechanism, comprising:

[0006] Fixings;

[0007] A rotating bearing member, rotatably connected to the fixing member;

[0008] A driving assembly, the driving assembly includes a body and an extension shaft extending from the body, the body and the extension shaft are relatively rotatable along the axis of the extension shaft, the body is fixedly connected to the rotating bearing member, and the extension shaft passes through the rotating bearing member and is fixedly connected to the fixing member.

[0009] In the rotating mechanism, the extension shaft is fixed in the fixing member to form a fixed position, and the body can rotate relative to the extension shaft along the axis of the extension shaft. The rotating bearing member is fixedly connected to the body so as to follow the body to form a rotational motion along the axis of the extension shaft. Compared with the design of the prior art in which the body is fixed and the extension shaft rotates, the body of the drive assembly is directly fixed to the rotating bearing member and drives the rotating bearing member to rotate, which can reduce the use of connecting accessories, simplify the structure of the rotating mechanism and help reduce the size; the rotating bearing member does not have to be connected to the driving assembly through a transmission structure, the structure of the rotating mechanism is compact, the radial size of the rotating mechanism along the extension shaft is reduced, the space utilization rate is high, the overall size of the rotating mechanism is reduced, space is saved, and it is conducive to the miniaturization development trend of the rotating mechanism.

[0010] Wherein, the driving assembly includes a motor, the extension shaft is the output shaft of the motor, the body is the casing of the motor, one end of the casing has a mounting surface for fixedly connecting the rotating carrier, and the output shaft of the motor extends axially outward from the mounting surface and is fixedly connected to the fixing member.

[0011] The driving component has a simple structure and a small size.

[0012] Wherein, the driving assembly includes a motor and a reducer, the motor is connected to the reducer, the reducer is arranged on the rotating carrier, the body includes the casing of the motor and the shell of the reducer, the extension shaft includes the output shaft of the motor and the output shaft of the reducer, and the output shaft of the reducer is fixed to the fixing member.

[0013] In the drive assembly, the reducer can adjust the torque of the motor to a suitable range to meet the drive requirements.

[0014] Wherein, one end of the output shaft of the reducer is mounted on the fixing member along the vertical direction, and the output shaft of the motor is vertically connected to the output shaft of the reducer;

[0015] The lower end of the reducer housing includes a first mounting surface, and the upper end of the reducer housing includes a second mounting surface. The first mounting surface faces the rotating bearing member and is fixedly connected to the rotating bearing member, and the second mounting surface is perpendicularly arranged to the first mounting surface and is fixedly connected to the housing of the motor.

[0016] In this layout, the output shaft of the motor is fixedly matched with the output shaft of the reducer. Since one end of the output shaft of the reducer is fixedly connected to the fixing member to form a fixed state, the output shaft of the motor is connected to the other end of the output shaft of the reducer through a bevel gear assembly. When the motor is working, the fixing member stops the rotation of the output shaft of the reducer, so the rotational torque of the motor will drive the motor casing to rotate. The rotating motor casing applies a radial force parallel to the second mounting surface to the reducer casing, and the radial force will drive the reducer casing to rotate along the output shaft of the reducer, thereby driving the rotating bearing member fixedly connected to the casing of the reducer to rotate; the output shaft of the motor and the output shaft of the reducer are arranged vertically, which can reduce the axial dimension of the rotating mechanism along the output shaft of the reducer, so that the height space occupied by the rotating mechanism is smaller.

[0017] In addition, the rotating bearing member and the fixing member are located on the same side of the first mounting surface, which can simplify the structure between the rotating bearing member and the fixing member, thereby making the structure between the rotating bearing member and the fixing member more compact.

[0018] Wherein, a side of the rotating bearing component facing away from the fixing component is spaced apart from the motor along the axial direction of the extension shaft.

[0019] The motor and the side of the rotating carrier facing away from the fixed member are arranged at an axial spacing along the extension axis, which can avoid contact between the motor and the rotating carrier, thereby preventing the motor from affecting the effective material bearing area or effective connection area on the rotating carrier, and preventing interference between the motor and the material or connected structure on the rotating carrier.

[0020] Wherein, the rotating mechanism further comprises:

[0021] A shaft sleeve seat, arranged on the fixing member;

[0022] The expansion sleeve is arranged in the sleeve seat, the outer wall of the expansion sleeve is tightly fitted in the sleeve seat, the inner wall of the expansion sleeve is surrounded to form an inner hole, the extension shaft is received in the inner hole, and the inner hole and the extension shaft are interference fit.

[0023] The expansion sleeve and the reducer rotor, and the expansion sleeve and the shaft sleeve seat are tightly matched and fixed by friction, without any assembly gap. The above connection method replaces the traditional key connection method, solves the gap problem caused by the key connection between the reducer and the fixing part, reduces mechanical errors, and can reduce the noise generated when the rotating mechanism is working.

[0024] The outer wall of the expansion sleeve is in a frustoconical shape, and the sleeve seat is provided with a conical hole matched with the outer wall of the expansion sleeve.

[0025] The gravity of the reducer and the rotating bearing member will drive the expansion sleeve to be further inserted downward into the bearing seat, thereby improving the matching effect between the expansion sleeve and the bearing seat.

[0026] Wherein, the inner hole is a stepped hole, and the end surface of the extension shaft abuts against the stepped surface of the stepped hole.

[0027] After the rotating mechanism is assembled, the end face of the reducer's rotor abuts against the step surface of the step hole, so as to increase the influence of the reducer's gravity on the matching effect of the expansion sleeve and the sleeve seat through direct contact with the expansion sleeve, thereby ensuring the fixing effect of the expansion sleeve and the sleeve seat.

[0028] Wherein, the rotating mechanism further comprises:

[0029] The bearing is arranged between the fixed component and the rotating bearing component, the inner ring of the bearing is connected to the fixed component, and the outer ring of the bearing is connected to the rotating bearing component.

[0030] The rotating bearing is supported by the bearing, and the rotating bearing is connected to the fixed component in rotation. The structure is simple and is conducive to reducing the resistance encountered by the rotating bearing when rotating.

[0031] Wherein, the outer ring of the bearing and the fixing member are arranged at intervals along the axial direction of the extension shaft;

[0032] The inner ring of the bearing is spaced apart from the rotating bearing member along the axial direction of the extension shaft.

[0033] The outer ring of the bearing and the fixing member are spaced apart along the axial direction of the extension shaft to avoid contact between the outer ring of the bearing and the fixing member, thereby reducing the friction force on the rotating bearing member during rotation, so that the rotating bearing member rotates more smoothly.

[0034] Similarly, the inner ring of the bearing and the rotating bearing are spaced apart along the axial direction of the extension shaft to avoid contact between the inner ring of the bearing and the rotating bearing, thereby reducing the friction force on the rotating bearing when rotating, so that the rotating bearing rotates more smoothly.

[0035] Wherein, the driving component further includes:

[0036] A mounting plate is arranged on a side of the rotating bearing member facing the fixing member, a portion of the machine body passes through the rotating bearing member and is connected to the mounting plate, and the extension shaft passes through the mounting plate.

[0037] By setting up a mounting plate, part of the main body of the driving assembly can be inserted into the rotating carrier, thereby improving the positioning effect of the driving assembly and the rotating carrier; in addition, the mounting plate and part of the main body are installed using the space between the rotating carrier and the fixing member, which is beneficial to reducing the overall axial size of the rotating mechanism along the extension axis.

[0039] A base,

[0040] A fixing member, fixed to the base, the fixing member comprising a receiving portion;

[0044] The rotating mechanism has a compact structure and a small size, which is conducive to the application of the construction equipment in a narrow construction environment, making the construction equipment more widely used.

[0045] Beneficial effects: The present invention provides a rotating mechanism and construction equipment.

[0065] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0066] This embodiment provides a rotating mechanism, such as Figure 1 and Figure 2 As shown, the rotating mechanism includes a fixing member 1, a rotating bearing member 2 and a driving assembly 3. The fixing member 1 is used to install the rotating mechanism at a specified position in the construction equipment; the rotating bearing member 2 is rotatably connected to the fixing member 1, and the rotating bearing member 2 is used to connect the target member that needs to be rotated. The driving assembly 3 can drive the rotating bearing member 2 to rotate relative to the fixing member 1 to drive the target member to rotate.

[0067] In this embodiment, the driving assembly 3 includes a body and an extension shaft extending from the body, the body is fixedly connected to the rotating bearing member 2, the extension shaft passes through the rotating bearing member 2 and is connected to the fixing member 1, and the body and the extension shaft can rotate relative to each other along the axis of the extension shaft. The extension shaft is fixed on the fixing member 1 to form a fixed position, and the rotating bearing member 2 is fixedly connected to the body so as to rotate with the body around the extension shaft. Compared with the design in the prior art that the body is fixed and the extension shaft rotates, the body of the driving assembly 3 is directly fixed to the rotating bearing member 2 and drives the rotating bearing member 2 to rotate, which can reduce the use of connecting accessories, simplify the structure of the rotating mechanism and help reduce the size; the rotating bearing member 2 does not need to be connected to the driving assembly 3 through a transmission structure, which can reduce the radial size of the rotating mechanism along the extension shaft, further reduce the overall size of the rotating mechanism, and is conducive to the miniaturization development trend of the rotating mechanism.

[0068] In addition, the rotating carrier 2 rotates around the extension axis, and the body of the driving component 3 is arranged around the extension axis, so that the driving component 3 can be arranged as close to the rotation center of the rotating carrier 2 as possible, which is beneficial to reducing the radial size of the driving component 3 exceeding the rotating carrier 2 along the extension axis, thereby reducing the radial size of the rotating mechanism as a whole along the extension axis; because there must be space for placing materials or connecting target parts above the rotating carrier 2, compared with arranging the body of the driving component 3 between the rotating carrier 2 and the fixed part 1, the body in this embodiment is installed using the space above the rotating carrier 2, which is beneficial to reducing the distance between the fixed part 1 and the rotating carrier 2, thereby reducing the axial size of the rotating mechanism as a whole along the extension axis; the rotating mechanism has a compact structure, which greatly saves the space occupied by the rotating mechanism.

[0069] like Figure 3 As shown, the driving assembly 3 includes a motor 31 and a reducer 32. The body includes a housing of the motor 31 and a housing of the reducer 32, the housing of the motor 31 is fixedly connected to the housing of the reducer 32, the output shaft of the motor 31 is drivingly connected to the output shaft of the reducer 32, and the housing of the reducer 32 is fixedly arranged on the rotating bearing 2. The extension shaft includes the output shaft of the motor 31 and the output shaft of the reducer 32, and the output shaft of the reducer 32 is connected to the fixing member 1 along one end of the vertical direction. The reducer 32 can adjust the output speed of the motor 31 to a suitable range to drive the rotating bearing 2 to rotate and prevent the material from being thrown out.

[0070] Specifically, the lower end of the shell of the reducer 32 includes a first mounting surface 321, and the upper end of the shell of the reducer 32 includes a second mounting surface 322. The first mounting surface 321 faces the rotating carrier 2 and is fixedly connected to the rotating carrier 2, and the second mounting surface 322 is perpendicular to the first mounting surface 321 and is fixedly connected to the casing of the motor 31.

[0071] Since one end of the output shaft of the reducer 32 is fixedly connected to the fixing member 1 to form a fixed state, the output shaft of the motor 31 is connected to the other end of the output shaft of the reducer 32 through the bevel gear assembly. When the motor 31 is working, the fixing member 1 stops the rotation of the output shaft of the reducer 32. Therefore, the rotational torque of the motor 31 will drive the casing of the motor 31 to rotate. The rotating casing of the motor 31 applies a radial force parallel to the second mounting surface 322 to the casing of the reducer 32. The radial force will drive the casing of the reducer 32 to rotate along the output shaft of the reducer 32, thereby driving the rotating bearing member 2 fixedly connected to the casing of the reducer 32 to rotate.

[0072] The first mounting surface 321 is directly fixed to the rotating support 2, and the second mounting surface 322 is directly fixed to the housing of the motor 31, which simplifies the connection structure between the drive component 3, the rotating support 2 and the fixing component 1, helps to make the structure of the rotating mechanism more compact, thereby reducing the space occupied by the drive component 3.

[0073] The output shaft of the motor 31 is arranged perpendicularly to the output shaft of the reducer 32 , which can reduce the axial dimension of the rotating mechanism along the output shaft of the reducer 32 , so that the height space occupied by the rotating mechanism is smaller.

[0074] In other embodiments, the drive assembly may not be provided with a reducer, as long as the output torque of the motor meets the requirements. In this case, the body is the housing of the motor, and the housing has a mounting surface, which is fixedly connected to the rotating bearing. The output shaft of the motor is an extension shaft, which extends axially outward from the mounting surface and is fixed to the fixing member.

[0075] Optionally, the fixed member 1 and the rotating bearing member 2 can be rotationally connected via a slewing support member, thereby reducing the resistance encountered by the rotating bearing member 2 during rotation, making the rotating bearing member 2 rotate more smoothly and reducing the driving energy required for the rotating bearing member 2 to rotate.

[0076] Specifically, the rotary support member may be a bearing 4, which includes an inner ring 42, an outer ring 41, and a rolling body 43 disposed between the inner ring 42 and the outer ring 41, wherein the rolling body 43 may be a ball or a roller. The bearing 4 is disposed between the fixed member 1 and the rotating bearing member 2, the inner ring 42 of the bearing 4 is connected to the fixed member 1, and the outer ring 41 of the bearing 4 is connected to the rotating bearing member 2. The rotating bearing member 2 is supported by the bearing 4, and the rotating connection between the rotating bearing member 2 and the fixed member 1 is realized, the structure is simple, and it is conducive to reducing the resistance encountered by the rotating bearing member 2 when rotating.

[0077] Furthermore, the outer diameter of the outer ring 41 of the bearing 4 can be set larger to improve the stability of the support for the rotating carrier 2. The output shaft of the reducer 32 is located in the inner ring 42 of the bearing 4, making full use of the space in the bearing 4 and making the structure of the rotating mechanism more compact.

[0078] Preferably, the rotating bearing member 2 may be a circular plate, and the outer diameter of the circular plate may be the same as the outer diameter of the outer ring 41 of the bearing 4 , so as to improve the stability of the rotating bearing member 2 .

[0079] In addition, the rotating carrier 2 is a circular plate, the center of which is located on the axis of the output shaft of the reducer 32. This can reduce the size of the rotating carrier 2 and the space required during the rotation process while keeping the supporting area of ​​the rotating carrier 2 unchanged, so as to further reduce the occupied area of ​​the rotating mechanism.

[0080] like Figure 3and Figure 4 As shown, the outer ring 41 of the bearing 4 can be fixedly connected to the rotating bearing member 2 by fasteners such as screws, so that the rotating bearing member 2 and the outer ring 41 of the bearing 4 rotate synchronously; the inner ring 42 of the bearing 4 can be fixedly connected to the fixing member 1 by fasteners such as screws, so that the fixing member 1 and the inner ring 42 of the bearing 4 remain stationary; through the rolling elements 43 in the bearing 4, the relative rotation of the inner ring 42 and the outer ring 41 can be achieved, thereby realizing the rotational connection between the rotating fixing member 1 and the rotating bearing member 2.

[0081] Furthermore, the outer ring 41 of the bearing 4 is spaced apart from the fixing member 1 along the axial direction of the output shaft of the reducer 32 to avoid contact between the outer ring 41 of the bearing 4 and the fixing member 1, thereby reducing the friction force on the rotating bearing member 2 during rotation, so that the rotating bearing member 2 can rotate more smoothly.

[0082] Similarly, the inner ring 42 of the bearing 4 is spaced apart from the rotating carrier 2 along the axial direction of the output shaft of the reducer 32 to avoid contact between the inner ring 42 of the bearing 4 and the rotating carrier 2, thereby reducing the friction force on the rotating carrier 2 during rotation, so that the rotating carrier 2 can rotate more smoothly.

[0083] In addition, the above arrangement also allows the inner ring 42 and the outer ring 41 of the bearing 4 to have a certain height difference along its axial direction, which can appropriately increase the distance between the rotating bearing 2 and the fixing member 1, thereby providing sufficient installation space for the connection between the output shaft of the reducer 32 and the fixing member 1.

[0084] To facilitate the connection between the reducer 32 and the rotating bearing 2, as shown in Figure 4 As shown, the drive assembly 3 further includes a mounting plate 33, which is disposed on the side of the rotating bearing member 2 facing the fixed member 1 and is used to support the reducer 32. The housing of the reducer 32 is connected to the mounting plate 33, and the output shaft of the reducer 32 passes through the mounting plate 33 so as to be connected to the fixed member 1. By providing the mounting plate 33, part of the housing of the reducer 32 can be passed through the rotating bearing member 2, thereby improving the positioning effect of the reducer 32 and the rotating bearing member 2; in addition, the mounting plate 33 and part of the housing of the reducer 32 are installed using the space between the rotating bearing member 2 and the fixed member 1, which is conducive to reducing the axial dimension of the entire rotating mechanism along the extension axis.

[0085] Optionally, the housing of the reducer 32 and the mounting plate 33 can be connected by screws, and the mounting plate 33 and the rotating bearing member 2 can be connected by screws, which has a simple structure and is easy to disassemble and assemble.

[0086] like Figure 3 , Figure 5 and Figure 6As shown, in order to facilitate the connection between the output shaft of the reducer 32 and the fixing member 1, the rotating mechanism further includes a connecting assembly 5, which connects the output shaft of the reducer 32 and the fixing member 1. Specifically, the connecting assembly 5 includes a sleeve seat 52 and an expansion sleeve 51, the sleeve seat 52 is arranged on the fixing member 1, the inner wall of the expansion sleeve 51 surrounds to form an inner hole, the expansion sleeve 51 is arranged in the sleeve seat 52, the outer wall of the expansion sleeve 51 is tightly fitted in the sleeve seat 52, and the inner wall of the expansion sleeve 51 is interference fit with the output shaft of the reducer 32.

[0087] In this embodiment, after the connecting assembly 5 is assembled with the reducer 32 and the fixing member 1 respectively, the expansion sleeve 51 and the output shaft of the reducer 32, and the expansion sleeve 51 and the sleeve seat 52 are both interference fit, fixed by friction, and there is no assembly gap. The above connection method replaces the traditional key connection method, solves the gap problem caused by the key connection between the reducer 32 and the fixing member 1, reduces mechanical errors, and can reduce the noise generated when the rotating mechanism is working.

[0088] Furthermore, the outer wall of the expansion sleeve 51 is in a frustoconical shape, and the sleeve seat 52 is provided with a tapered hole adapted to the outer wall of the expansion sleeve 51. After the rotating mechanism is assembled, the housing of the reducer 32 is fixed to the mounting plate 33 by screws, which will generate a downward force on the reducer 32, thereby driving the output shaft of the reducer 32 to further fit tightly with the expansion sleeve 51, and at the same time driving the expansion sleeve 51 to fit tightly with the sleeve seat 52, thereby increasing the friction between the expansion sleeve 51 and the output shaft of the reducer 32, and between the expansion sleeve 51 and the sleeve seat 52, thereby improving the fixing effect.

[0089] In addition, the gravity of the reducer 32 and the rotating bearing 2 will also drive the expansion sleeve 51 to be further inserted downward into the bearing 4 seat, thereby improving the matching effect between the expansion sleeve 51 and the bearing 4 seat.

[0090] Furthermore, if Figure 6 and Figure 8 As shown, the inner hole of the expansion sleeve 51 is a stepped hole. After the rotating mechanism is assembled, the end face of the output shaft of the reducer 32 abuts against the step surface 513 of the stepped hole, so as to increase the influence of the gravity of the reducer 32 on the matching effect of the expansion sleeve 51 and the sleeve seat 52 through direct contact with the expansion sleeve 51, thereby ensuring the fixing effect of the expansion sleeve 51 and the sleeve seat 52.

[0091] like Figure 7 and Figure 8 As shown, the expansion sleeve 51 includes a left half sleeve 511 and a right half sleeve 512 which are arranged opposite to each other, and the left half sleeve 511 and the right half sleeve 512 are split structures. When the expansion sleeve 51 clamps the output shaft of the reducer 32, the left half sleeve 511 and the right half sleeve 512 are spliced, and there may be a gap between the two to ensure full contact with the output shaft of the reducer 32, improve the clamping effect, and also be compatible with the output shafts of the reducer 32 with different shaft diameters.

[0092] Optionally, the left half casing 511 and the right half casing 512 can be completely identical symmetrical structures, that is, the left half casing 511 and the right half casing 512 have the same radius and equal central angles, so as to increase the uniformity of force on the output shaft of the reducer 32 and avoid stress concentration or damage to the output shaft of the reducer 32 due to local uneven force.

[0093] In some embodiments, the left half casing 511 and the right half casing 512 may also be asymmetrically arranged, that is, the left half casing 511 and the right half casing 512 have the same radius but different central angles, with one side having a larger central angle and the other side having a smaller central angle.

[0094] In this embodiment, the input shaft of the reducer 32 is perpendicular to the output shaft of the reducer 32, and the output shaft of the motor 31 is connected to the input shaft of the reducer 32. That is, the output shaft of the motor 31 is perpendicular to the axis of the output shaft of the reducer 32. This layout can reduce the axial dimension of the rotating mechanism along the output shaft of the reducer 32, so that the height space occupied by the rotating mechanism is small.

[0095] Furthermore, in order to prevent the motor 31 from affecting the effective material-carrying area on the rotating carrier 2, the motor 31 and the side of the rotating carrier 2 facing away from the fixed part 1 are arranged axially spaced along the output shaft of the reducer 32 so that the motor 31 avoids the area on the rotating carrier 2 facing it, thereby preventing the motor 31 from interfering with the material.

[0096] like Fig. 9 As shown, this embodiment also provides a construction equipment, including a base 100, a rotating mechanism 200 and a turret 300. The rotating mechanism 200 includes a fixing member 1, a rotating bearing member 2 and a driving assembly 3. The fixing member 1 is fixed on the base 100, and the fixing member 1 includes a receiving portion. The rotating bearing member 2 is mounted on the fixing member 1, and the rotating bearing member 2 includes a through hole, and the receiving portion is exposed upward from the through hole. The driving assembly 3 includes a body and an extension shaft extending from the body, the body is fixed to the rotating bearing member 2, the extension shaft is fixedly connected to the receiving portion, and the driving assembly 3 drives the rotating bearing member 2 to rotate around the extension shaft through the body. The turret 300 is movably mounted on the rotating bearing member 2, and the turret 300 is used to connect and drive the operation execution mechanism.

[0097] In the above-mentioned construction equipment, the rotating mechanism 200 has a compact structure, and the driving component 3 does not need to be arranged between the fixed component 1 and the rotating bearing component 2, which is beneficial to reducing the distance between the fixed component 1 and the rotating bearing component 2. The structure is compact and greatly saves space; the body of the driving component 3 rotates with the rotating bearing component 2, which can avoid interference with the turret 300.

[0098] It should be noted that the rotating mechanism 200 may adopt the structure of the above-mentioned rotating mechanism, wherein the receiving portion may be a connecting component.

[0099] In this embodiment, the operation execution mechanism is a grabbing mechanism 400, which can grab materials so as to transport the materials or install the materials to a specific location.

[0100] Specifically, the turret 300 includes a tower 301 and a lifting assembly 302 disposed on the tower 301. The tower 301 is vertically disposed, and its bottom end is fixed on the rotating bearing 2. The lifting assembly 302 is disposed on the tower 301 and can drive the grasping mechanism 400 to rise and fall, thereby adjusting the grasping position height of the grasping mechanism 400.

[0101] like Fig. 9 and Fig.10 As shown, the grabbing mechanism 400 includes a telescopic arm 401 and a grabbing assembly 402. The telescopic arm 401 is adjustable in length, one end of which is mounted on the output end of the lifting assembly 302, and the other end is used to mount the grabbing assembly 402. By extending and retracting the telescopic arm 401, the grabbing range of the grabbing assembly 402 can be adjusted.

[0102] The grab assembly 402 includes a crossbeam, a fixed clamping plate arranged at one end of the crossbeam in the length direction, and a movable clamping plate arranged at the other end of the crossbeam in the length direction, and the movable clamping plate can move relative to the crossbeam in the length direction of the crossbeam to cooperate with the fixed clamping plate to clamp or release the material. Further, the grab assembly also includes a grab driving member, which is arranged on the crossbeam and is used to drive the movable clamping plate to approach or move away from the fixed clamping plate in the length direction of the crossbeam to automatically grab or release the material.

[0103] Optionally, the grabbing driving member may be a linear motor, a cylinder or a hydraulic cylinder, as long as it can drive the movable clamping plate to move back and forth along the length direction of the crossbeam.

[0104] like Fig.10 As shown, the telescopic arm 401 includes a fixed arm 4011 and a movable arm 4012. The fixed arm 4011 and the movable arm 4012 have the same extension direction, one end of the fixed arm 4011 is mounted on the output end of the lifting assembly 302, the movable arm 4012 is arranged on the fixed arm 4011, and can move relative to the fixed arm 4011 along its extension direction, and the crossbeam of the grabbing assembly 402 is arranged on the movable arm 4012. Through the cooperation of the movable arm 4012 and the fixed arm 4011, the grabbing range of the grabbing assembly 402 can be adjusted as needed, and can also be shortened when the grabbing mechanism 400 is not working to reduce the occupied space.

[0105] Furthermore, the telescopic arm 401 also includes a telescopic driving member 4013 , and the telescopic driving member 4013 is used to drive the movable arm 4012 to slide along the fixed arm 4011 to achieve the extension and contraction of the telescopic arm 401 .

[0106] Optionally, the telescopic driving member 4013 may be a linear motor, a cylinder or a hydraulic cylinder, as long as it can drive the movable arm 4012 to move back and forth along its extension direction.

[0107] like Fig.11 and Fig.12 As shown, the lifting assembly 302 includes a lifting motor (not shown in the figure), a driving pulley 3021, a driven pulley 3022, a transmission belt 3023, a lead screw 3024 and a grabbing mounting seat 3025. The lead screw 3024 is rotatably arranged on the tower 301 and extends in the vertical direction, the grabbing mounting seat 3025 is threadedly matched with the lead screw 3024, and the grabbing mechanism 400 is installed on the grabbing mounting seat 3025. The driven pulley 3022 is coaxially arranged and fixed with the lead screw 3024, the lifting motor is arranged on the tower 301, the driving pulley 3021 is coaxially arranged and fixed with the output shaft of the lifting motor, and the transmission belt 3023 is connected to the driving pulley 3021 and the driven pulley 3022 in a transmission manner. After the lifting motor rotates, the driving pulley 3021, the driven pulley 3022 and the transmission belt 3023 cooperate to drive the lead screw 3024 to rotate, thereby driving the grasping mechanism 400 to rise and fall by driving the grasping mounting seat 3025 to rise and fall.

[0108] In this embodiment, the lifting motor and the lead screw 3024 can be arranged on opposite sides of the tower 301 to make the structure of the turret 300 more compact. The lifting motor cooperates with the lead screw 3024 through the pulley assembly, so that the lead screw 3024 and the lifting motor can be arranged in parallel, which is conducive to reducing the height of the tower 301 and making the tower 301 more stable.

[0109] To facilitate the installation of the lead screw 3024 , an upper mounting frame 3011 and a lower mounting frame 3012 are provided on the tower 301 , and the upper and lower ends of the lead screw 3024 are rotatably connected to the upper mounting frame 3011 and the lower mounting frame 3012 through bearings, respectively.

[0110] Furthermore, a avoidance groove is provided at the bottom end of the tower 301, and the driving assembly 3 in the rotating mechanism 200 is arranged in the avoidance groove.

[0111] Furthermore, the axis of the extension shaft of the rotating mechanism 200 coincides with the axis of the lead screw 3024 , so that the centers of gravity of the rotating mechanism 200 and the tower 301 are located on the same vertical line, which is beneficial to improving the stability of the construction equipment.

[0112] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
