Abstract
Description
Technical Field
[0001] This utility model relates to the field of top beam welding technology, specifically a locking and positioning component for welding the top beam of a hydraulic support. Background Technology
[0002] As a key piece of equipment to ensure operational safety and efficiency, the structural strength and assembly precision of the top beam of a hydraulic support directly affect its overall performance. The top beam of a hydraulic support is mostly formed by welding. During the welding process, the top beam needs to be precisely fixed by locking and positioning components to prevent the top beam from shifting or deforming due to welding stress, and to ensure that the welding positions of components such as stiffeners and main plates meet the design requirements. Therefore, reliable locking and positioning components are the core auxiliary devices in the welding and processing of the top beam of a hydraulic support.
[0003] The existing Chinese patent document CN209006935U discloses a locking and positioning device for welding the top beam of a hydraulic support, which includes an axis positioning assembly parallel to the short side of a rectangular welding platform and a locking and positioning assembly. The axis positioning assembly includes a positioning shaft and positioning shaft seats located at the left and right ends of the positioning shaft. The locking and positioning assembly includes a locking mechanism and a positioning mechanism. The locking mechanism and the positioning mechanism cooperate with each other to position the stiffening plate of the top beam of the hydraulic support. This utility model has the advantages of simple structure and accurate positioning.
[0004] However, most of the locking and positioning devices in the above-mentioned solutions and existing technologies still have room for optimization in practical applications. In particular, they lack buffer components for the positioning process of the top beam. When the top beam is placed on the positioning component or when it undergoes slight displacement due to thermal expansion and contraction during welding, the existing devices mostly use rigid contact positioning and lack a buffer protection structure for the top beam. This not only easily leads to surface damage between the top beam and the positioning component due to hard collision, but may also affect the positioning stability due to the inability to adapt to the slight deformation of the top beam, thus potentially affecting the welding accuracy.
[0005] Therefore, this utility model proposes a locking and positioning assembly for welding the top beam of a hydraulic support to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a locking and positioning assembly for welding the top beam of a hydraulic support, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a locking and positioning assembly for welding the top beam of a hydraulic support, comprising a base, a support leg, and a top beam, wherein the bottom end of the base is provided with the support leg, and the top beam is mounted on the base; The base is provided with a positioning component, a buffer component, and a fixing component. The positioning component is located at both ends of the base, the buffer component is located at the head end of the base, and the fixing component is located on the buffer component.
[0008] Preferably, the sliding groove in the positioning component is disposed on the base, a top beam is slidably installed in the sliding groove, and a snap-fit protrusion is provided at the end of the top beam.
[0009] Preferably, the positioning blocks in the positioning assembly are evenly distributed on both sides of the base, and a positioning protrusion is fixedly provided on the positioning block, with the bottom end of the positioning protrusion closely attached to the top of the snap-fit protrusion.
[0010] Preferably, the bottom of the buffer protrusion in the buffer assembly is provided with a sliding rod, which is adapted to slide and engage with the second sliding groove, which is located at the end of the base.
[0011] Preferably, a spring is fixedly provided at the bottom end of the fixing pin in the fixing component, and the other end of the spring is fixedly provided inside the fixing hole. The fixing hole is provided at both ends of the sliding rod, and the fixing pin fixes the sliding rod to the fixing hole. The fixing hole is provided on the base.
[0012] Preferably, the rotating shaft in the securing component is fixedly installed at the tail end of the base, and a securing rod is sleeved on the rotating shaft. The securing rod is in close contact with the snap-fit protrusion at the tail end of the top beam.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a positioning component, a buffer component, and a fixing component on the base, a multi-dimensional synergistic locking and positioning structure is formed, which effectively solves the problems existing in the prior art. The positioning component realizes the smooth sliding installation of the top beam by means of the sliding groove on the base. With the positioning blocks on both sides of the base and the positioning protrusions on them tightly attached to the locking protrusion at the end of the top beam, the lateral and vertical displacement of the top beam can be restricted, ensuring the initial positioning accuracy of the top beam during welding. The buffer component, through the matching locking of the sliding rod at the bottom of the buffer protrusion with the sliding groove at the end of the base, can provide sliding buffer space when the top beam is placed or the thermal expansion and contraction during welding causes a small displacement, avoiding surface damage to the top beam caused by rigid contact. The fixing component, through the cooperation of the fixing pin and the spring in the fixing hole on the sliding rod, and the tight attachment of the fixing rod sleeved on the base tail shaft to the locking protrusion at the tail of the top beam, can not only compensate for the small displacement through the spring force, but also further strengthen the positioning of the tail of the top beam, ensuring the positioning stability of the top beam during welding, and ultimately improving the overall quality and reliability of the welding of the hydraulic support top beam.

Detailed Implementation
[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0017] Example 1: Please refer to Figures 1-2 A locking and positioning assembly for welding the top beam of a hydraulic support includes a base 1, a support leg 2, and a top beam 3. The support leg 2 is provided at the bottom end of the base 1, and the top beam 3 is installed on the base 1. A positioning assembly 4, a buffer assembly 5, and a fixing assembly 6 are provided on the base 1. The positioning assembly 4 is provided at both ends of the base 1, the buffer assembly 5 is provided at the head end of the base 1, and the fixing assembly 6 is provided on the buffer assembly 5.
[0018] The sliding groove 401 in the positioning component 4 is set on the base 1, and the top beam 3 is slidably installed in the sliding groove 401. The end of the top beam 3 is provided with a snap-fit protrusion 402.
[0019] In use, first place the support leg 2 stably on the welding site to ensure that the base 1 is in a horizontal state, laying a stable foundation for subsequent positioning. Then, the operator aligns the top beam 3 to be welded with the sliding groove 401 of the positioning component 4 on the base 1, and slowly pushes the top beam 3 so that it slides smoothly along the sliding groove 401 until the snap-fit protrusion 402 at the end of the top beam 3 moves to the preset positioning position. During this process, the sliding groove 401 provides a precise sliding guide for the top beam 3, preventing the top beam 3 from shifting during installation. This initially achieves the pre-fixation of the position of the top beam 3 on the base 1, preparing for further reinforcement by the buffer component 5 and the sturdy component 6. At the same time, it facilitates the operator to quickly adjust the top beam 3 to the initial position required for welding.
[0020] Example 2: Based on Example 1, please refer to... Figures 2-3The positioning blocks 403 in the positioning component 4 are evenly arranged on both sides of the base 1. The positioning blocks 403 are fixedly provided with positioning protrusions 404, and the bottom end of the positioning protrusions 404 is in close contact with the top of the snap-fit protrusions 402.
[0021] The bottom of the buffer protrusion 501 in the buffer assembly 5 is provided with a sliding rod 502. The sliding rod 502 is adapted to slide and engage with the sliding groove 503. The sliding groove 503 is located at the end of the base 1.
[0022] In use, after the top beam 3 slides along the sliding groove 401 to the preset position, observe the positioning blocks 403 of the positioning components 4 at both ends of the base 1. Ensure that the positioning protrusions 404 on the positioning blocks 403 are tightly fitted with the top of the snap-fit protrusions 402 at the end of the top beam 3. The positioning protrusions 404 limit the snap-fit protrusions 402, thus restricting the vertical displacement of the top beam 3. Combined with the lateral displacement restricted by the sliding groove 401, the top beam 3 is accurately positioned. Next, check the installation status of the buffer component 5 at the end of the base 1. Push the buffer protrusion 501 so that the sliding rod 502 at its bottom slides along the sliding groove 503 at the end of the base 1 until the buffer protrusion 501 contacts the head of the top beam 3. The buffer protrusion 501 will firmly maintain the buffer during the welding of the top beam 3, avoiding direct rigid contact between the top beam 3 and the base 1, which could cause surface damage.
[0023] Example 3: Based on Example 2, please refer to... Figures 3-4 A spring 602 is fixedly installed at the bottom end of the fixing pin 601 in the fastening component 6. The other end of the spring 602 is fixedly installed inside the fixing hole 603. The fixing hole 60 is installed at both ends of the sliding rod 502. The fixing pin 601 fixes the sliding rod 502 to the fastening hole 606, which is installed on the base 1.
[0024] The rotating shaft 604 in the stabilizing component 6 is fixedly installed at the tail end of the base 1. A stabilizing rod 605 is sleeved on the rotating shaft 604. The stabilizing rod 605 is tightly attached to the snap-fit protrusion 402 at the tail of the top beam 3.
[0025] In use, after the buffer protrusion 501 of the buffer assembly 5 contacts the head of the top beam 3, the fixing pin 601 of the fastening assembly 6 is stretched, causing the fixing pin 601 to stretch the spring 602 at its bottom end. After the sliding rod 502 is adjusted to a suitable position, the fixing pin 601 is released, and the spring 602 returns to its original position, pushing the fixing pin 601 into the fixing holes 603 at both ends of the sliding rod 502 and then into the fastening hole 606, thus achieving relative fixation between the sliding rod 502 and the base 1, thereby fixing the position of the buffer protrusion 501. The fastening rod 605 is rotated, and the fastening rod 605 has a stop adjustment. During the welding of the top beam 3, the fastening rod 605 will not shift. Only after forcefully rotating the fastening rod 605 can its restriction on the top beam 3 be released. The fixing pin 601 is firmly connected, and the fastening rod 605 continuously restricts the locking protrusion 402, providing double protection for the stable positioning of the top beam 3 and ensuring accurate welding operations.
