[0002] In the automobile manufacturing process, it is usually necessary to use a conveyor chain to move a trolley and the car body loaded on the trolley so as to transport the car body to the corresponding process area for corresponding processing.

[0003] Conveyor chains are divided into horizontal chains and slope chains, such as Figure 1 As shown, a pusher head 200 is usually hinged on the horizontal chain and the inclined chain, and every two pusher heads 200 form a group. The two pusher heads 200 in the same group are arranged opposite to each other, and the first end of the pusher head 200 sinks under the action of gravity, and the second end is tilted upward. The trolley cross beam 600 can be clamped between the second ends of the two pusher heads 200, so that the trolley and the vehicle body carried on the trolley can be driven to move while the chain moves.

[0004] If the conveyor chain fails and stops running without taking temporary emergency measures, the car body will have abnormal quality due to the process time exceeding the preset time, and even the entire car body will be scrapped. Therefore, when the conveyor chain fails, the trolley crossbeam 600 needs to be pushed out from between the two push heads 200, that is, the trolley is moved out of the process area to avoid the process time of the car body on the trolley being too long, and at the same time facilitate the subsequent maintenance of the conveyor chain.

[0005] However, before pushing the trolley cross beam 600 out from between the two push heads 200, the angle of the push head 200 needs to be adjusted so that the first end of the push head 200 is lifted up and the second end is lowered, and the push head 200 is generally horizontal as a whole, so that the trolley cross beam 600 can pass over the push head 200. However, in the prior art, there is basically no tool for adjusting the angle of the push head 200, so a push head adjustment tool for conveyor chain failure is urgently needed to solve the above problem.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Embodiment 1

[0045] like Figure 2-Figure 5 As shown, this embodiment provides a pusher head adjustment tool for conveyor chain faults, including a main tool, and the main tool includes a mounting seat 1, an adjustment component 2, a first positioning component 3 and a second positioning component 4. The mounting seat 1 can be mounted on the chain track groove 100. The adjustment component 2 includes an adjustment member 21 and an elastic member 22, the middle part of the adjustment member 21 is hinged to the mounting seat 1, the adjustment end of the adjustment member 21 can support the first end of the pusher head 200, the upper end of the elastic member 22 is connected to the retaining end of the adjustment member 21, and the lower end of the elastic member 22 is connected to the mounting seat 1. The first positioning component 3 is installed on the mounting seat 1, and is used to limit the movement of the mounting seat 1 along the length direction of the chain track groove 100. The second positioning component 4 is installed on the mounting seat 1, and is used to limit the movement of the mounting seat 1 along the width direction of the chain track groove 100.

[0046] The pusher head adjustment tool for conveyor chain failure provided in this embodiment can, when the conveyor chain fails, first set the mounting seat 1 on the chain track groove 100, and press the second end of the pusher head 200 down, and then push the main tool to move in the direction close to the pusher head 200. When the main tool moves to a suitable position, release the second end of the pusher head 200 so that the first end of the pusher head 200 is placed on the adjustment end of the adjustment member 21 under the action of gravity. Since the retaining end of the adjustment member 21 is connected to the elastic member 22, under the pulling force of the elastic member 22, the adjustment end of the adjustment member 21 can support the first end of the pusher head 200, so that the pusher head 200 is kept in a roughly horizontal state, so as to push the trolley cross beam 600 from above the pusher head 200, that is, move the trolley out of the process area, avoid the processing time of the car body on the trolley being too long, ensure the processing quality of the car body, and at the same time facilitate the subsequent maintenance of the conveyor chain and improve the maintenance efficiency; by adjusting the elastic force of the elastic member 22 , which is conducive to making the adjustment part 21 adapt to push heads 200 of different shapes and weights. At the same time, when the trolley beam 600 passes over the push head 200, it can have a certain resilience to prevent hard interference between the trolley beam 600 and the push head 200, and avoid affecting the accuracy of the trolley beam 600; in addition, by setting the first positioning component 3, the mounting seat 1 can be prevented from moving in the length direction of the chain track groove 100, that is, the front and rear directions are fixed, and by setting the second positioning component 4, the mounting seat 1 can be prevented from moving in the width direction of the chain track groove 100, that is, the left and right directions are fixed. Through the cooperation of the first positioning component 3 and the second positioning component 4, the main tool can be firmly and securely fixed on the chain track groove 100, preventing the main tool from being displaced during the movement of the trolley beam 600, and thus keeping the push head 200 in a roughly horizontal state at all times, which is conducive to the trolley beam 600 passing smoothly over the push head 200.

[0047] The pusher head adjustment tool for conveyor chain faults provided in this embodiment has a simple structure, small size, light weight, is easy to process and manufacture, and has a low manufacturing cost. It is quick to install and fix, and is not restricted by space during installation and disassembly, thus saving chain stop time and greatly reducing fault handling time. In addition, the pusher head 200 and the trolley crossbeam 600 will not be deformed during use, thereby extending the service life.

[0048] like Figure 2-Figure 3 Combination Figure 5-Figure 6 As shown, the adjustment member 21 includes a lever 211 and a cushion block 212. The middle part of the lever 211 is hinged to the mounting seat 1. One end of the lever 211 is connected to the cushion block 212, and the other end is connected to the upper end of the elastic member 22. The cushion block 212 can support the first end of the pusher head 200. Using the cushion block 212 to support the first end of the pusher head 200 is conducive to ensuring the stability of the support. Specifically, in this embodiment, the cushion block 212 is rectangular.

[0049] like Figure 6 As shown, the lever 211 includes a first rod 2111, a second rod 2112 and a third rod 2113. The first end of the first rod 2111 is connected to the lower end of the second rod 2112, the first end of the third rod 2113 is connected to the upper end of the second rod 2112, the second end of the first rod 2111 and the second end of the third rod 2113 extend to both sides of the second rod 2112 respectively, the second end of the first rod 2111 is connected to the cushion block 212, the second end of the third rod 2113 is connected to the upper end of the elastic member 22, and the middle part of the third rod 2113 is hinged to the mounting seat 1. That is, the lever 211 is roughly Z-shaped. Further, as Figure 5 As shown, the inclined surface of the first end of the push head 200 can be placed on the connection between the second rod 2112 and the third rod 2113, which is helpful to judge whether the main tool is placed in place and ensure the stability of the support of the push head 200.

[0050] In this embodiment, the mounting base 1 is in the shape of a rectangular plate, and the chain track groove 100 is used as a horizontal support point. The rectangular main body is designed to be more stable in force, and the installation and disassembly are simple and easy to operate.

[0051] like Figure 2-Figure 3 Combination Figure 6 As shown, the mounting seat 1 is provided with an escape groove 11, which is used to escape the adjustment end of the adjustment member 21 and the first end of the push head 200. By providing the escape groove 11, a certain adjustment space can be given to the adjustment member 21, so that the adjustment member 21 can flexibly adapt to different push heads 200. Specifically, in this embodiment, the escape groove 11 is in a "convex" shape. The escape groove 11 can escape the pad 212, the first rod 2111, the second rod 2112 and the first end of the push head 200.

[0052] like Figure 2-Figure 3 Combination Figure 6 As shown, the adjustment assembly 2 further includes an upper connecting member 23, which is mounted on the third rod 2113, and the upper end of the elastic member 22 is hooked on the upper connecting member 23. Further, the adjustment assembly 2 further includes a lower connecting member 24, which is mounted on the mounting seat 1, and the lower end of the elastic member 22 is hooked on the lower connecting member 24. Further, the mounting seat 1 is provided with a groove, and the lower connecting member 24 is mounted on the bottom of the groove.

[0053] In this embodiment, the elastic member 22 is a spring.

[0054] like Figure 2-Figure 3 Combination Figure 7As shown, the first positioning assembly 3 includes a positioning rod 31 and a limit adjustment structure, the first end of the positioning rod 31 is hinged to the mounting seat 1, and the second end extends to the bottom of the mounting seat 1. The limit adjustment structure is arranged at the bottom of the mounting seat 1, and the limit adjustment structure is used to adjust the angle of the positioning rod 31 so that the second end of the positioning rod 31 can abut against the side of the chain link shaft 300 close to the push head 200. By the second end of the positioning rod 31 abutting against the side of the chain link shaft 300 close to the push head 200, the mounting seat 1 can be limited to move away from the push head 200 along the chain track groove 100, thereby ensuring the position accuracy and working stability of the main tool. By setting the limit adjustment structure, the angle of the positioning rod 31 can be adjusted according to the length of the chain link and the diameter of the chain link shaft 300, so that the positioning rod 31 can be adjusted to a suitable angle and maintained at the angle. In addition, in the slope chain, by the positioning rod 31 abutting against the side of the chain link shaft 300 close to the push head 200, the main tool can also be prevented from falling off the chain track groove 100 due to the slope.

[0055] like Figure 3 As shown, the limit adjustment structure includes a limit stopper 33 and an adjustment rod 34. The limit stopper 33 is arranged at the bottom of the mounting seat 1, and the angle between the limit surface of the limit stopper 33 and the bottom surface of the mounting seat 1 is an acute angle. The adjustment rod 34 is movably mounted on the limit stopper 33 in a direction close to or away from the positioning rod 31, and the positioning rod 31 can abut against the adjustment rod 34. By abutting the positioning rod 31 with the adjustment rod 34, the angle of the positioning rod 31 can be limited, so that the positioning rod 31 is kept at a desired angle.

[0056] Specifically, in this embodiment, the adjustment rod 34 is a screw rod, and by rotating the screw rod, the length of the abutting end of the screw rod extending out of the limit stopper 33 can be adjusted, thereby achieving adjustment and limitation of the angle of the positioning rod 31 .

[0057] Furthermore, the first positioning assembly 3 further includes a torsion spring 32, a first end of which is fixedly connected to the mounting seat 1, and a second end of which extends along the length direction of the positioning rod 31 and abuts against the positioning rod 31. The second end of the torsion spring 32 can apply downward pressure to the positioning rod 31, and cooperates with the limit adjustment structure to help ensure the stability of the angle of the positioning rod 31.

[0058] like Figure 7 As shown, the positioning rod 31 is provided with a mounting groove 311, and the second end of the torsion spring 32 is clamped in the mounting groove 311. The mounting groove 311 is provided to help ensure the stability and reliability of the installation of the torsion spring 32.

[0059] Furthermore, a slope 312 is provided on the second end of the positioning rod 31, and the slope 312 can abut against the side of the chain link shaft 300 close to the push head 200. The provision of the slope 312 is conducive to better abutment with the cylindrical surface of the chain link shaft 300.

[0060] Furthermore, a mounting hook is provided on the first end of the torsion spring 32 , and the mounting hook can be hooked on the mounting seat 1 to ensure the reliability of the installation of the torsion spring 32 .

[0061] like Figure 2-Figure 3 Combination Figure 5 The second positioning assembly 4 includes a first positioning member 41 and a second positioning member 42 mounted on the mounting seat 1. The first positioning member 41 can abut against the first inner side wall of the chain track groove 100, and the second positioning member 42 can abut against the second inner side wall of the chain track groove 100. That is, the first positioning member 41 and the second positioning member 42 can be clamped in the chain track groove 100 along the width direction of the chain track groove 100, thereby limiting the movement of the mounting seat 1 along the width direction of the chain track groove 100.

[0062] Further, the first positioning member 41 and the second positioning member 42 are both bolts. By screwing the bolts, the length of the bolts extending downward from the mounting seat 1 can be adjusted.

[0063] Embodiment 2

[0064] The difference between this embodiment and the first embodiment is that the pusher adjustment tool for conveyor chain failure provided in this embodiment includes not only the main tool provided in the first embodiment but also an auxiliary tool. A conveyor cover plate 400 is usually installed on the chain track groove 100 of the horizontal chain, and a conveyor groove 500 is provided on the conveyor cover plate 400. Since the main tool cannot be directly pushed to move on the chain track groove 100 after the conveyor cover plate 400 is installed, an auxiliary tool is needed to drive the main tool to move so that the main tool supports the pusher head 200.

[0065] For example Figure 8-Figure 10 As shown, one end of the auxiliary tool provided in this embodiment can pass through the conveying groove 500 on the conveying cover 400, and the other end can be connected to the main tool to drive the main tool to move along the length direction of the chain track groove 100, so that the adjustment end of the adjustment member 21 can support the first end of the push head 200.

[0066] It should be pointed out that after the conveying cover 400 is covered on the chain track groove 100, the second end of the push head 200 can be pressed down by using a pressure rod, and then the auxiliary tool can be used to push the main tool to move toward the push head 200. When the main tool moves to a suitable position, the pressure rod is released, so that the first end of the push head 200 is placed on the adjustment end of the adjustment member 21 under the action of gravity, that is, the adjustment end of the adjustment member 21 supports the first end of the push head 200.

[0067] Specifically, the auxiliary tool includes a traction handle 5 and a traction fork 6. The traction fork 6 is connected to one end of the traction handle 5. The traction handle 5 can pass through the conveying groove 500, and the traction fork 6 can fork the main tool. After the traction fork 6 forks the main tool, the traction handle 5 is pulled outside the conveying cover plate 400, so that the traction handle 5 drives the main tool to move on the chain track groove 100. Specifically, in this embodiment, the traction handle 5 is arc-shaped.

[0068] like Fig.10 As shown, the traction fork 6 can extend between the second rod 2112 and the upper connecting member 23. Since one tine of the traction fork 6 can abut against the connection between the first rod 2111 and the second rod 2112, and the other tine can abut against the connection between the third rod 2113 and the upper connecting member 23, the traction fork 6 can drag the main tool closer to or away from the push head 200.

[0069] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
