Referring to fig. 5 and 8, the inner wall of the bottom of the supporting cover 3 is rotatably connected with a first guiding shaft 5, the first guiding shaft 5 is located right above the working table 202, the inner wall of the top of the supporting cover 3 is rotatably connected with a fourth guiding shaft 801, a limiting block 506 is located between the sliding plate 501 and the first guiding shaft 5, the steel cable 306 is sequentially attached to the first guiding shaft 5, the second guiding shaft 502 and the fourth guiding shaft 801, the steel cable 306 is upward along the working table 202, the steel cable 306 firstly penetrates through the bottom of the supporting cover 3, is attached to the upper surface of the first guiding shaft 5, is attached to the lower surface of the second guiding shaft 502, is attached to the lower surface of the fourth guiding shaft 801, and is connected to the winding mechanism after penetrating through the top of the supporting cover 3.

When the upper beam of the elevator needs to be welded, firstly, two side beams 402 are placed on the workbench 202, then, a steel rope 306 is wound by a winding mechanism, the workbench 202 moves upwards along the first fixing rod 102, after the workbench is lifted to a proper height, the two side beams 402 are aligned, as shown in fig. 3 and 13, the two side beams 402 are horizontally placed, a connecting plate 403 is clamped between the two side beams 402, then, a worker welds the connecting plate 403 on the two side beams 402, and the upper beam of the elevator is manufactured.

As shown in fig. 3 and 12, the workbench 202 is designed with a hollow middle and an open end, and when welding, a worker stands on the open side of the workbench 202 to weld, and because the workbench 202 adopts the hollow middle, the welding is more convenient when welding the joint between the connecting plate 403 and the bottom of the side beam 402.

As shown in fig. 13, for the upper beam of the elevator, the connecting plates 403 and the side beams 402 are all made of concave steel, that is, channel steel, and the through holes formed on the side beams 402 are mounting holes, also called mounting positions, for mounting the car roof wheels or other components.

As shown in fig. 5-9, after the welding is completed, the workbench 202 is adjusted to a proper height by the winding mechanism, for example, the height from the bottom plate 1 is 50-100 cm, then the winding mechanism stops working, at this time, the cylinder 505 is started, the limiting block 506 is driven to move downwards and separate from the sliding plate 501, then the sliding plate 501 slides rapidly towards the first guide shaft 5 under the action of the tension force of the steel cable 306, at this time, the workbench 202 falls down rapidly and is equivalent to a free falling body, then collides with the bottom plate 1, so that the upper beam of the elevator receives an impact force, then the welded part of the side beam 402 and the connecting plate 403 is checked, whether the crack is realized or not is checked, further, whether the welded part is firm or not is checked, and further, when the load of the elevator suddenly increases and in the running process, the traction machine drives the upper beam of the elevator to vibrate by the steel cable 306, whether the upper beam of the elevator is safe enough, and safe and reliable running can be judged.

As shown in fig. 5, the distance between the sliding plate 501 and the first guide shaft 5 is greater than two thirds of the falling distance of the table 202, so that the sliding plate 501 is prevented from striking the first guide shaft 5 before the table 202 has not contacted the bottom plate 1.

In order to improve the sliding stability of the limiting block 506, as shown in fig. 9, a guide rod is fixedly connected between the bottom of the supporting cover 3 and the supporting plate 504, and the limiting block 506 slides on the guide rod.

As shown in fig. 1 and 2, an end of the first fixing lever 102 remote from the base plate 1 is fixed to the support frame 101.

As shown in fig. 3, two ends of the workbench 202 are rotatably connected with a bidirectional threaded rod 4, threads at two ends of the bidirectional threaded rod 4 are all the same in other parameters except for opposite screw threads, and two ends of the bidirectional threaded rod 4 are connected with a clamping plate 401; one end of the bidirectional threaded rod 4 is fixedly connected with a driving block 404, and 2-4 groups of driving holes are circumferentially distributed on the driving block 404.

When two boundary beams 402 are placed on the workbench 202, at this time, two ends of the boundary beams 402 are located between two clamping plates 401 on two sides of the workbench 202, after the connecting plates 403 are clamped between the two boundary beams 402, a worker inserts a crow bar into a driving hole on the driving block 404, then rotates to drive the bidirectional threaded rod 4 to rotate, the clamping plates 401 are driven to move towards the boundary beams 402, the boundary beams 402 are fixedly clamped, and the position of the connecting plates 403 is prevented from shifting during welding.

When the workbench 202 falls down rapidly to strike the bottom plate 1, the clamping plate 401 prevents the side beam 402 from being greatly displaced, and the impact resistance of the upper beam of the elevator is detected under the condition that the side beam 402 is fixed, because the upper beam of the elevator is relatively motionless in the process of generating vibration in the actual operation of the elevator.

A guide bar is fixedly connected to the table 202, and the clamping plate 401 slides on the guide bar synchronously.

It should be emphasized that the manual driving of the bi-directional threaded rod 4 is adopted to rotate, so as to clamp the edge beam 402, instead of other electrical components, mainly considering that the impact force generated during the process of the table 202 falling down rapidly to strike the bottom plate 1 can cause the electrical components to be damaged easily, and the reliability of the clamping manner without manual operation is high.

As shown in fig. 1, 2 and 10, considering that in the actual machining process, the bottom plate 1 is attached to the ground or has a very small vertical height with the ground, when the workbench 202 falls down quickly to strike the bottom plate 1, air between the two can be compressed to generate air flow, and the air flow is quickly diffused to the periphery.

The elevator for processing the upper beam of the elevator of the embodiment further comprises impact plates 201 sliding on the first fixing rods 102, four corners of the impact plates 201 are also connected to the 4 first fixing rods 102 in a sliding manner, one end of each impact plate 201 is also open, as shown in fig. 1, the open end of each impact plate 201 is on the same side as the open end of the workbench 202, so that the welding operation of workers is facilitated, and the impact plates 201 are positioned at the bottom of the workbench 202; the bottom plate 1 is fixedly connected with hydraulic cylinders 2, the output ends of the hydraulic cylinders 2 are fixedly connected with the lower surface of the impact plate 201, and the number of the hydraulic cylinders 2 is 2.

When the impact resistance of the welded upper beam of the elevator is detected, the hydraulic cylinder 2 is started to drive the impact plate 201 to move upwards, so that a certain distance between the impact plate 201 and the ground, for example, 60-100 cm is achieved, then the distance between the workbench 202 and the impact plate 201 is adjusted to be 50-100 cm, then the workbench 202 is driven to move to quickly fall down to impact the impact plate 201, the impact resistance is detected, meanwhile, due to the fact that a certain distance is produced between the impact plate 201 and the ground, air flow generated by the quick fall of the workbench 202 is spread around in parallel, at the moment, a certain distance is provided between the air flow and the ground, and dust on the ground is avoided.

Example 2:

referring to fig. 1 to 13, the overall solution is further optimized on the basis of example 1, substantially the same as in example 1.

The impact plate 201 is longer and wider than the table 202, and when the table 202 contacts the impact plate 201, the table 202 is positioned between 3 air inlet hoods 9 and does not contact the air inlet hoods 9.

When the air flow generated by the rapid falling of the workbench 202 is spread around in parallel, the air flow enters the air inlet cover 9, then is sprayed out from the air spraying holes on the air spraying seat 903 through the first pipeline 901 and the second pipeline 902, and when the workbench 202 contacts the impact plate 201, impact vibration occurs, so that the impact resistance of the upper beam of the elevator is checked, welding slag and other dust generated by welding are separated from the upper beam of the elevator after the processing is finished, namely, separated from the side beam 402 and the connecting plate 403, at the moment, the air spraying holes spray out the air flow to blow off the separated welding slag and other dust, and the purpose of cleaning the welding slag and other dust on the surface of the upper beam of the elevator is synchronously achieved by utilizing the generated air flow.

As shown in fig. 2 and 10, a limiting frame 904 is fixedly connected to the striking plate 201, and the second pipe 902 penetrates through the limiting frame 904.

The limiting frame 904 is composed of two vertical rods fixed on the impact plate 201 and a plurality of cross rods, wherein a cross rod is fixed between the tops of the two vertical rods, 3-5 cross rods are fixed below the middle of the two vertical rods, and the second pipeline 902 passes through between the two uppermost cross rods.
