DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0025] The hoisting equipment belongs to special equipment, and the brake beam track is an indispensable part in the hoisting equipment. The fixation of the brake beam track is a basic condition for ensuring the safe operation of the equipment, and therefore the daily maintenance of the brake beam track is very important. ​

[0026] In the prior art, the fastening and replacement of the rail track plate bolt of the brake beam track need to be completed by maintenance personnel using a mobile lifting platform regularly. Since the height of the brake beam track is relatively high, generally reaching 6 m, when the mobile lifting platform is used, the mobile lifting platform needs to be raised to the above height, and the bolt at the corresponding position is assembled manually. Since the personnel are located at a high place, the danger coefficient is high, and there is a safety hazard of falling from a high altitude.

[0027] Please refer to Figures 1 to 5 To solve the above technical problems, the bolt assembly device 100 is provided, wherein the bolt assembly device 100 comprises a connecting part 1, a supporting part 2 and a base 3. The connecting part 1 comprises a sleeve joint 11, the sleeve joint 11 has a fastening end 111 and a mounting end 112, the fastening end 111 is partially recessed inward to form a matching groove 111a, the matching groove 111a is used to connect with the bolt, the supporting part 2 is mounted in cooperation with the mounting end 112, and at least part of the structure extends in a first direction D, the first direction D is the axial direction of the bolt, so that the supporting part 2 has a length in the first direction D, at least part of the supporting part 2 extends in a second direction E, so as to provide torque for the connecting part 1 to drive the bolt to rotate around the first direction D, wherein the first direction D and the second direction E are arranged at an angle, the base 3 is arranged at the other end of the supporting part 2, and the base 3 is used to support the supporting part 2 on a supporting surface. The supporting surface can be the ground or the plane of other structural members.

[0028] Please refer to Figure 1The first direction D is the axial direction of the bolt, and the axial direction of the bolt is arranged in the vertical direction. The bolt assembly device 100 comprises a connecting portion 1, a supporting portion 2 and a base 3. The connecting portion 1 comprises a sleeve joint 11, and the sleeve joint 11 comprises a fastening end 111 and a mounting end 112. The fastening end 111 is recessed inward to form a matching groove 111a near one side of the bolt, and the matching groove 111a is used for matching assembly with the bolt head. The bolt assembly device 100 is convenient for subsequent installation, fastening or disassembly of the bolt. At least part of the supporting portion 2 extends in the first direction D, so that the supporting portion 2 has a length in the first direction D. The supporting portion 2 can be used to replace the lifting platform in the prior art. The operator does not need to move to the high lifting platform, and can operate the supporting portion to assemble the bolt at the brake beam track on the ground. Thus, the safety hazard of high-altitude operation is avoided. In addition, the supporting portion 2 has two end portions arranged opposite to each other in the first direction D. One end portion is connected with the mounting end 112 of the connecting portion 1. Thus, the supporting portion 2 can provide torque for the connecting portion 1 by rotating the supporting portion 2, so as to drive the rotation of the sleeve joint 11. In addition, the bolt assembly device 100 further comprises the base 3 arranged at the other end portion of the supporting portion 2 and opposite to the connecting portion 1. The base 3 is used for supporting the supporting portion 2. The bolt assembly device 100 can be placed on the ground, so as to improve the convenience of operating the supporting portion 2. In the application, the bolt is assembled, fastened and disassembled by the connecting portion 1, the supporting portion 2 and the base 3. The structure is simple, the operation is convenient, and the safety hazard is reduced.

[0029] More specifically, please refer to Figures 2 to 3 In the application, the fastening end 111 has a plurality of matching grooves 111a arranged in the first direction D in sequence. In the first direction D, the cross-sectional areas of the plurality of matching grooves 111a gradually decrease. Specifically, the plurality of matching grooves 111a are arranged in the first direction D in sequence. The matching grooves 111a with smaller cross-sectional areas are arranged closer to the mounting end 112. The bolt can be matched with the bolt. It can be understood that, in the first direction D, the cross-sectional contour of the matching groove 111a is a hexagon, which corresponds to the shape of the bolt head, so as to be matched with the bolt. In other embodiments, the sleeve joint 11 is detachably connected with the supporting portion 2. For different shapes of the bolt head, the sleeve joint 11 with a corresponding shape can be replaced to install, fasten and disassemble the bolt. Thus, the application range of the bolt assembly device 100 is widened. In addition, in the embodiment, the number of the matching grooves 111a is multiple. The matching grooves 111a are arranged in sequence in the direction from the fastening end 111 to the mounting end 112, and the areas of the matching grooves 111a gradually decrease. Thus, one sleeve joint 11 can be applied to bolts with different sizes. The size of the matching groove 111a is matched with the size of the conventional bolt. The structure is simple. Thus, the bolt assembly device 100 can be applied to different scenes, so as to improve the versatility and flexibility of the device itself.

[0030] It can be understood that in the embodiments of the present application, the inner wall of the matching groove 111a is provided with a buffer, and in some embodiments, the buffer is made of flexible material such as silica gel or rubber. The buffer is used to buffer the collision between the bolt and the matching groove 111a, so as to avoid damage to the bolt or the matching groove 111a, thereby prolonging the service life of the bolt assembly device 100 and achieving the protection effect of the bolt. In addition, since the bolt assembly device 100 needs to tighten the bolt, the buffer can also be interference-fitted to increase the friction between the matching groove 111a and the bolt, thereby facilitating the tightening of the bolt.

[0031] Referring to Figure 4 As can be seen from the content, the support part 2 includes a hollow support pipe 21, one end of the support pipe 21 is inserted and matched with the mounting end 112 of the connecting part 1, and the other end of the support pipe 21 is connected with the base 3. It can be understood that in other embodiments, the support pipe 21 and the sleeve joint 11 can be connected in a detachable manner such as threaded device, magnetic attraction, buckle, etc., which is not limited in the present application. In the present application, the advantages of the plug-in matching mode of the support pipe 21 and the mounting end 112 are that the plug-in assembly is simple, the sleeve joint 11 can be quickly replaced or disassembled, and the plug-in mode can transmit torque through the sleeve matching part, which facilitates the support pipe 21 to transmit torque to the sleeve joint 11. In addition, in other embodiments, the support part 2 can also be provided as a support rod or a support plate, which is not limited herein. In the present application, the support part 2 is provided as a support pipe 21, which has the advantages of reducing cost and ensuring that the weight of the bolt assembly device 100 is small, which is convenient for moving and rotating.

[0032] In addition, in the embodiments of the present application, part of the support part 2 is telescopic in the second direction E, so as to provide variable torque to the connecting part 1 by the support part 2. It can be understood that for different bolts and different application scenarios, the torque provided by the support part 2 to the connecting part 1 is different, so that the support part 2 can be elongated or shortened along the second direction E according to the actual situation, so as to provide different torque to the bolt. When the support part 2 is elongated along the second direction E, the moment arm can be increased, and when the same force is used, the torque can be increased, which is convenient for screwing the bolt. Conversely, when the support part 2 is shortened, the torque can be reduced.

[0033] Further, referring to Figures 4 to 5The support pipe 21 comprises a first support section 211, a second support section 212 and a third support section 213 connected in sequence, wherein the first support section 211 is arranged to extend along the first direction D, and the first support section 211 is provided with a protrusion 211a at an end close to the connecting part 1, as shown in Figure 5 the protrusion 211a is provided with a matching protrusion 211b at the outer periphery thereof, the protrusion 211a is inserted into the mounting end 112, the second support section 212 is connected to an end of the first support section 211 away from the mounting end 112, the second support section 212 extends along the second direction E and is telescopic in the second direction E, the third support section 213 also extends along the first direction D, and the third support section 213 is connected to the other end of the second support section 212; wherein the first direction D is perpendicular to the second direction E.

[0034] Please refer to Figure 5 It can be understood that the first support section 211 is used to be connected to the socket 11, and therefore the first support section 211 is provided with a protrusion 211a at an end close to the connecting part 1, and the mounting end 112 of the socket 11 is partially recessed inward to form an insertion interface, the protrusion 211a is used to be inserted into the insertion interface, and also facilitates the installation and replacement of the socket 11. In addition, the protrusion 211a is provided with a matching protrusion 211b at the outer periphery thereof, the matching protrusion 211b is used to increase the contact area between the protrusion 211a and the mounting end 112 of the socket 11, so as to facilitate better transmission of torque, and the shape of the matching protrusion 211b can be set as an arc surface or a rectangular plane. When the shape of the matching protrusion 211b is set as an arc surface, the contact area with the mounting end 112 can be further increased, thereby facilitating the transmission of torque, and also reducing the degree of wear of the corners. When the matching protrusion 211b is set as a rectangular plane, the processing cost of the protrusion 211a can be reduced, thereby facilitating production and manufacturing.

[0035] In addition, please continue to refer to Figure 4, the second support section 212 is arranged in extension along the second direction E and is retractable in the second direction E to increase or decrease the moment, so in actual work, the operator does not need to stand directly below the bolt to operate the bolt assembly device 100, and the operator can work on the side of the bolt, which can ensure the safety of the operator and prevent the operator from being injured when the bolt falls from a high place, and on the other hand, the operator can more conveniently observe the installation state of the bolt due to the angle of the line of sight. In addition, the second support section 212 arranged in the second direction E allows the operator to install, tighten and disassemble the bolt with less force. The third support section 213 is arranged in extension along the first direction D, and in the embodiment of the application, the length of the third support section 213 is the longest, and the third support section 213 is used to bear most of the height between the operator and the brake beam track, so that the bolt assembly device 100 of the application can replace the lifting platform to complete the maintenance work on the ground.

[0036] Further, the length of the second support section 212 is D1, wherein 30 cm≤D1≤50 cm. It can be understood that when the length of the second support section 212 is less than 30 cm, the length is too short to form a safe distance for the operator protection, and the advantage of the lever force arm is not obvious at this time, and when the length of the second support section 212 is greater than 50 cm, the length is too long, occupies a large space, is not convenient to place, and also increases the cost, therefore, when the length of the second support section 212 is 30 cm to 50 cm, the workload of the operator can be reduced and the manufacturing cost of the device can be reduced under the premise of ensuring the safety of the operator.

[0037] It can be understood that please refer to Figure 4, the second support section 212 includes a first telescopic section 212a and a second telescopic section 212b, the first telescopic section 212a is connected to the first support section 211, the second telescopic section 212b is connected to the third support section 213, and the first telescopic section 212a is adjustable in position relative to the second telescopic section 212b in the second direction, the support part 2 further includes a supporting section 214, the supporting section 214 is telescopically arranged, one end of the supporting section 214 is movably arranged on the first telescopic section 212a, and the other end of the supporting section 214 is movably arranged on the third support section 213, because the second support section 212 is arranged in extension in the second direction E during the process of bolt assembly and fastening, the second support section 212 will bear a larger torque, especially when the second support section 212 is elongated, the risk of breakage will increase, therefore, in order to achieve the effect of reinforcement, the supporting section 214 is further arranged in the application scheme, the supporting section 214 is used for supporting and stabilizing the second support section 212, the supporting section 214 can actually include mechanical structures such as telescopic rods, hinges and supporting rods, sliding rails and sliding supports to realize the telescoping and movement of the supporting section 214, so as to cooperate with the telescoping of the second support section 212, specifically, in the application, the supporting section 214 is arranged as a telescopic rod, one end of the telescopic rod is hingedly connected to the first telescopic section 212a of the second support section 212, and the other end of the telescopic rod is clamped to the third support section 213, a plurality of grooves, protrusions or hooks are correspondingly arranged at the third support section 213, so that the end of the telescopic rod is clamped, therefore, the length of the telescopic rod can be adjusted according to different needs of force, so that the end of the telescopic rod is clamped with grooves, protrusions or hooks at different positions, thereby achieving the supporting effect of the second support section 212 and reducing the safety hazards in the process of bolt assembly and disassembly.

[0038] At the same time, please refer to Figure 4 , the support part 2 further includes a fourth support section 215, one end of the fourth support section 215 is connected to the first telescopic section 212a, the other end of the fourth support section 215 is slidably arranged relative to the base 3, and the fourth support section 215 can slide on the base according to the telescoping of the second support section 212 in the second direction, thereby achieving the effect of supporting the second support section 212 and providing support for the connecting part 11 in the first direction.

[0039] Optionally, the fourth support section 215 and the supporting section 214 can exist at the same time, thereby achieving a better supporting and reinforcing effect on the second support section 212, in other embodiments, only the fourth support section 212 or only the supporting section 214 can be arranged to support the second support section 212, which is not limited in the application.

[0040] In addition, please refer toFigure 4 The support part 2 is in a square shape. In other embodiments, the support part 2 can also be in a cylindrical shape.
