Description

Technical Field

[0001] This utility model relates to the field of elevator shaft welding technology, and in particular to a welding and fixing frame for the ladder inside the elevator shaft. Background Technology

[0002] In the current factory welding process for elevator shaft frames, the upper and lower crossbeams are primarily connected and fixed by welding vertical beams. Since the crossbeams are typically quite long, several vertical beams need to be fixed to them to ensure overall frame stability. During welding, the crossbeams are first suspended in designated positions, followed by the welding of the vertical beams. However, the lack of effective fixing measures necessitates additional personnel to support the vertical beams, increasing labor costs. Furthermore, manual support makes it difficult to guarantee the absolute stability of the vertical beams' positions; slight errors can affect welding accuracy, negatively impacting the overall quality of the elevator shaft frame. Additionally, it is difficult to make precise adjustments to the vertical beam positions within a small range during welding, making it impossible to ensure a suitable and uniform spacing between adjacent vertical beams, thus limiting the production efficiency and quality improvement of the elevator shaft frame.

[0027] Example 1

[0028] Reference Figures 1-5This is the first embodiment of the present utility model. This embodiment provides a welding and fixing frame for a ladder inside a hoistway car. The welding and fixing frame for a ladder inside a hoistway car includes a main component 100, including an upper crossbeam 101, a lower crossbeam 102 and a vertical beam 103. The lower crossbeam 102 is disposed below the upper crossbeam 101, and the vertical beam 103 is fixed to the upper crossbeam 101 by welding.

[0029] The elevator shaft frame is formed by welding together the upper crossbeam 101, the lower crossbeam 102, and the vertical beam 103. This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0030] The fixing component 200 is disposed on the upper crossbeam 101 and includes a fixing member 201. The fixing member 201 includes a clamping plate 201a, a first threaded rod 201b, and a second threaded rod 201c. The clamping plate 201a is located on one side of the upper crossbeam 101. The clamping plate 201a has a first threaded hole 201a-1, and the first threaded rod 201b is inserted into the first threaded hole 201a-1. The clamping plate 201a has a second threaded hole 201a-2, and the second threaded rod 201c is inserted into the second threaded hole 201a-2.

[0031] Both the upper crossbeam 101 and the lower crossbeam 102 are equipped with fasteners 201.

[0032] The first threaded rod 201b is used to bring the clamping plates 201a on both sides of the upper crossbeam 101 closer to each other, thereby clamping the upper crossbeam 101. The threads at both ends of the first threaded rod 201b rotate in opposite directions, so that when the first threaded rod 201b rotates, the clamping plates 201a on both sides of the upper crossbeam 101 can move closer or further away at the same time.

[0033] The threads at both ends of the second threaded rod 201c rotate in opposite directions. Through the cooperation of the second threaded hole 201a-2, it is used to bring the clamping plate 201a on one side of the upper crossbeam 101 and the clamping plate 201a on the lower crossbeam 102 closer to each other, thereby bringing the upper crossbeam 101 and the lower crossbeam 102 closer together in a small range to enhance the reliability of welding.

[0034] The fixing component 200 also includes a clamping member 202, which is disposed on the upper crossbeam 101. It includes a clamping plate 202a, a fixing plate 202b, and a third threaded rod 202c. The clamping plate 202a is disposed on one side of the vertical beam 103, and the fixing plate 202b is fixed on the clamping plate 202a. The fixing plate 202b has a third threaded hole 202b-1, and the third threaded rod 202c is inserted into the third threaded hole 202b-1.

[0035] By setting the clamping part 202, the vertical beam 103 can be supported and fixed during spot welding, thereby enhancing the accuracy of welding.

[0036] The clamping plate 202a is shaped like a zigzag and can move along the direction of the upper crossbeam 101. There are four clamping plates 202a in total, divided into two groups. The upper crossbeam 101 and the lower crossbeam 102 each correspond to a group of clamping plates 202a. The upper crossbeam 101 and the lower crossbeam 102 are clamped from both sides by the two clamping plates 202a, thereby determining the position of the vertical beam 103.

[0037] The third threaded rod 202c is used to ensure that the clamping plate 202a fits against the surface of the upper crossbeam 101. The threads at both ends of the third threaded hole 202b-1 rotate in opposite directions. Through the cooperation between the third threaded hole 202b-1 and the third threaded rod 202c, when the third threaded rod 202c is rotated, the fixing plates 202b and the clamping plate 202a on both sides of the upper crossbeam 101 will move closer to the upper crossbeam 101 in sync, so that the clamping plate 202a fits against the surfaces on both sides of the upper crossbeam 101.

[0038] Example 2

[0039] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the clamping component 202 also includes a fixed block 202d, a rotating column 202e, and a movable block 202f. The fixed block 202d is fixed on the clamping plate 202a, the rotating column 202e is rotatably connected to the fixed block 202d, and the movable block 202f is sleeved on the rotating column 202e.

[0041] The fixed block 202d is used to support and position the rotating column 202e. There are two moving blocks 202f on one rotating column 202e. The rotating column 202e is used to drive the moving blocks 202f to move closer or further away synchronously.

[0042] Specifically, the rotating column 202e has threads at both ends, and the threads at both ends have opposite helical directions.

[0043] The movable block 202f has a spiral groove corresponding to the rotating column 202e. The rotating column 202e is threadedly connected to the movable block 202f. When the rotating column 202e rotates, the movable blocks 202f on both sides will move closer or further away synchronously. When the end face of the movable block 202f is in contact with the surface of the vertical beam 103, the movable block 202f will restrict the relative movement of the vertical beam 103 between the upper crossbeam 101 and the lower crossbeam 102.

[0044] Specifically, a handle 202g is fixed to one side of the rotating column 202e.

[0045] The handle 202g is designed to drive the rotating column 202e to rotate.

[0046] Specifically, a connecting plate 202h is provided on the movable block 202f, and a threaded post 202i is fixed on the connecting plate 202h.

[0047] The connecting plate 202h and the moving block 202f are connected by bolts 202k. The connecting plate 202h is used to connect the moving blocks 202f corresponding to the upper crossbeam 101 and the lower crossbeam 102, so that the two moving blocks 202f can move synchronously.

[0048] Specifically, a support plate 201d is fixed on the card plate 201a, and a rotating sleeve 201e is provided on the support plate 201d. The support plate 201d and the rotating sleeve 201e are connected by a bearing.

[0049] The support plate 201d is used to support and position the rotating sleeve 201e, and the rotating sleeve 201e is used to drive the threaded column 202i to move horizontally.

[0050] Example 3

[0051] Reference Figures 1-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0052] Specifically, the threaded post 202i is inserted into the rotating sleeve 201e.

[0053] The rotating sleeve 201e has a thread corresponding to the threaded post 202i. When the rotating sleeve 201e is rotated, the threaded post 202i will move along the direction of the rotating sleeve 201e, thereby causing the moving block 202f to move along the direction of the upper crossbeam 101 and the lower crossbeam 102. The movement of the moving block 202f will synchronously drive the vertical beam 103 to move, thereby allowing the vertical beam 103 to move within a small range to ensure the distance requirement between adjacent vertical beams 103 and improve welding accuracy.

[0054] Specifically, there are four card plates 201a, divided into two groups. Two card plates 201a are set on each side of the upper crossbeam 101, and two card plates 201a are set on each side of the lower crossbeam 102.

[0055] Specifically, a contact plate 202j is fixed on the fixing plate 202b.

[0056] One end face of the contact plate 202j can contact the surface of the vertical beam 103. Rotating the third threaded rod 202c makes the clamping plate 202a fit against the surface of the upper crossbeam 101. Then, rotating the rotating column 202e makes the end face of the moving block 202f fit against the surface of the vertical beam 103. At this time, the contact plate 202j fits against the surface of the vertical beam 103. Through the cooperation of the moving block 202f and the contact plate 202j, the vertical beam 103 is stably fixed between the upper crossbeam 101 and the lower crossbeam 102.

[0057] The contact point between the vertical beam 103 and the lower horizontal beam 102 is not obstructed. After the vertical beam 103 is fixed, the welding workers can spot weld the connection part of the vertical beam 103, thereby improving the welding accuracy and ensuring the overall quality and stability of the elevator shaft frame.

[0058] Specifically, there are two of each of the first threaded rod 201b and the second threaded rod 201c.

[0059] In use, first, bring a set of clamping plates 201a close to each other from both sides of the upper crossbeam 101, ensuring that the first threaded rod 201b is aligned with the first threaded hole 201a-1. Then, rotate the first threaded rod 201b to make the clamping plate 201a fit against the surface of the upper crossbeam 101. Perform the same operation on the corresponding clamping plate 201a on the lower crossbeam 102, while ensuring that the second threaded hole 201a-2 on the clamping plate 201a is aligned. Rotate the second threaded rod 201c to bring the clamping plates 201a on the upper crossbeam 101 and the lower crossbeam 102 close to each other and contact the upper surfaces of the upper crossbeam 101 and the lower crossbeam 102. In this way, relying on the friction of the clamping plate 201a in contact with the upper crossbeam 101 and the lower crossbeam 102, it is ensured that the support plate 201d will not move relative to the upper crossbeam 101 and the lower crossbeam 102, thus providing reliable positioning for the clamping member 202.

[0060] Then, move the clamping plate 202a to both sides of the upper crossbeam 101 and the lower crossbeam 102, rotate the third threaded rod 202c to bring the clamping plates 202a on both sides closer to each other, so that the clamping plates 202a are in contact with the surface of the upper crossbeam 101. Then, turn the handle 202g to drive the rotating column 202e to rotate, so that the end face of the moving block 202f is in contact with the surface of the vertical beam 103. At this time, the contact plate 202j is in contact with the surface of the vertical beam 103. Through the cooperation of the moving block 202f and the contact plate 202j, the vertical beam 103 is stably vertical between the upper crossbeam 101 and the lower crossbeam 102.

[0061] When a small adjustment of the position of the vertical beam 103 is required, the rotating sleeve 201e is rotated, and the threaded column 202i will move along the direction of the rotating sleeve 201e, thereby causing the moving block 202f to move along the direction of the upper crossbeam 101 and the lower crossbeam 102. The movement of the moving block 202f will synchronously drive the vertical beam 103 to move, thereby allowing the vertical beam 103 to move within a small range to ensure the required distance between adjacent vertical beams 103.

[0062] After the position of the vertical beam 103 is determined, the welder tack welds the connection part of the vertical beam 103. After the tack welding is completed and the position is determined, the third threaded rod 202c and the rotating column 202e can be rotated in the opposite direction to move the entire fixing device away from the vertical beam 103 so that the final welding can be carried out.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
