Description

TECHNICAL FIELD

[0001] The utility model belongs to elevator accessory processing equipment technical field, especially relates to the roll and place positioning frock based on elevator compensating chain processing. BACKGROUND

[0002] The elevator compensating chain is used for connecting the car and the counterweight of the elevator, balancing the weight of the electric rope and the running cable, and is a component for balancing the operation of the elevator. The commonly used silent elevator compensating chain products mainly include plastic coated compensating chains and all-plastic compensating chains. After the PVC plastic is coated on the two types of products through the respective extrusion process, the finished compensating chains are generally led out through the movable traction bridge, and are stacked and rolled into a circular structure on the workshop floor by manual operation, so that the stress can be released and the subsequent winding and packaging machine can be facilitated.

[0003] However, the manual rolling and placing method on the ground not only easily causes the compensating chains to be contaminated with dust, but also easily causes the stacked and rolled compensating chains to be skewed due to the absence of reference and limiting structures, thereby affecting the subsequent winding and packaging. If the compensating chains produced in the same batch are long, the number of stacked layers is too high, and the lateral collapse is easily caused. CONTENT OF THE UTILITY MODEL

[0023] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the following will be further described in detail by combining with examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0024] Example one

[0025] In order to solve the technical problems in the background art, the following roll and positioning tool based on elevator compensation chain processing is given:

[0026] As shown in the figure, Figure 1 And Figure 2 The roll and positioning tool based on elevator compensation chain processing comprises a round pad 1, the top surface center of the round pad 1 is axially detachably provided with a positioning column 2, the outer surface is vertically detachably provided with at least four limiting plates 4 at equal intervals, and the top surface of the limiting plate 4 is flush with the top surface of the positioning column 2.

[0027] By adopting the above technical scheme, compared with directly rolling on the workshop floor, the round pad 1 in the roll and positioning tool provides a cleaner and smoother rolling platform, reduces the opportunity of direct contact between the compensation chain and the floor, and reduces the risk of dust contamination;

[0028] The positioning column 2 is located at the top surface center of the round pad 1 and is axially detachable, so that the positioning column 2 can be reasonably selected according to the required stacking height of different batches of compensation chains, so as to ensure that the center of the stacked and rolled compensation chain can be accurately aligned with the positioning column 2, thereby realizing the center positioning of the compensation chain in the stacking process;

[0029] At least four limiting plates 4 are arranged on the outer circumferential surface of the circular pad 1 at equal intervals and vertically, which not only limits the movement of the compensation chain in the horizontal direction and prevents the side collapse phenomenon caused by stacking too high, but also ensures that the compensation chain can always be kept on a flat circular surface when stacking, avoiding the phenomenon of skew and chaotic stacking, because the top surface of the limiting plate 4 is flush with the top surface of the positioning column 2.

[0030] The detachable design of the positioning column 2 and the limiting plate 4 makes the tooling flexible to adapt to the length of different batches of compensation chains, without the need to customize special tooling for each batch of compensation chains, thereby reducing production costs and inventory pressure.

[0031] Embodiment two

[0032] In combination Figure 1 , Figure 3 , Figure 4 and Figure 6 , on the basis of the above embodiment, the present embodiment further gives the following contents:

[0033] In the present embodiment, as shown in Figure 1 , Figure 4 and Figure 6 , at least four "I" shaped slots 11 are radially arranged at equal intervals on the bottom surface of the circular pad 1, and the plug-in plate 3 is radially slidably inserted into the slot 11, and the end surface of the plug-in plate 3 is detachably connected vertically to the bottom of the limiting plate 4.

[0034] The outer part of the circular pad 1 can be concentrically sleeved with a number of circular gaskets 5 according to the length of the radial extension of the plug-in plate 3 around it, and the top surface of the circular gasket 5 is flush with the top surface of the circular pad 1, and the inner vertical surface of the plug-in plate 3 is vertically attached to the outer circumferential surface of the outermost circular gasket 5.

[0035] By adopting the above technical scheme, the slots 11 are radially arranged at equal intervals on the bottom surface of the circular pad 1, providing a sliding insertion space for the plug-in plate 3. This design allows the position of the limiting plate 4 to be adjusted flexibly according to the length and stacking requirements of different batches of compensation chains. By sliding the position of the plug-in plate 3 in the slot 11, the distance between the limiting plate 4 and the center of the circular pad 1 can be changed, and by increasing or decreasing the number of circular gaskets 5 concentrically sleeved on the outer part of the circular pad 1, the stacking height requirement of different length batches of compensation chains can be met. At the same time, the cooling and stress release effect of the newly produced compensation chain is directly proportional to the radius of the winding and unwinding, that is, the larger the radius of the winding and unwinding, the better the cooling and stress release effect.

[0036] The sliding insertion of the slot 11 and the plug-in plate 3, and the detachable connection of the plug-in plate 3 and the limiting plate 4, make the whole tooling easy to assemble and disassemble.

[0037] As shown in Figure 3 andFigure 4 As shown, the inner side of the slot 11 is fixed with a protruding rib 111, and the outer side of the insert plate 3 is provided with a groove 31 corresponding to the protruding rib 111.

[0038] By adopting the above technical scheme, the structure of the groove 31 and the protruding rib 111 allows the insert plate 3 to slide and insert along the protruding rib 111, thereby ensuring that the insert plate 3 can be stably inserted into the slot 11 and ensuring that the insert plate 3 is not easily separated from the round pad 1 when the round pad 1 is transferred;

[0039] By the cooperation of the protruding rib 111 and the groove 31, the position of the insert plate 3 in the slot 11 is effectively fixed, which not only prevents the insert plate 3 from loosening or deviating in the slot 11, but also increases the stability of the entire tool structure.

[0040] Embodiment Three

[0041] In combination Figures 1 to 5 As shown in the above embodiment, the present embodiment further provides the following contents:

[0042] In the present embodiment, as shown in the above embodiment, Figures 1 to 5 The end surface of the insert plate 3 is provided with a clamping member 6; the clamping member 6 includes a U-shaped clamping frame 61, the longitudinal portion of the U-shaped clamping frame 61 is vertically fixed to the end surface of the insert plate 3, and the center of the transverse portion of the U-shaped clamping frame 61 is vertically screwed with a fastening screw 62; the thickness of the U-shaped clamping frame 61 is the same as the thickness of the insert plate 3, and the distance between the two inner sides of the U-shaped clamping frame 61 is the same as the width of the limiting plate 4; the bottom of the limiting plate 4 is vertically inserted into the U-shaped clamping frame 61, and is fixedly attached to the end surface of the insert plate 3 by rotating and pressing the fastening screw 62.

[0043] By adopting the above technical scheme, the U-shaped clamping frame 61 in the clamping member 6 is a structure with a longitudinal portion and a transverse portion, the longitudinal portion is vertically fixed to the end surface of the insert plate 3, and the transverse portion is used to install the fastening screw 62; the design of the U-shaped clamping frame 61 allows it to closely fit on the insert plate 3, and at the same time provides a stable platform to fix the limiting plate 4;

[0045] The thickness of the U-shaped clamping frame 61 is the same as the thickness of the insert plate 3, and the distance between the two inner sides of the U-shaped clamping frame 61 is the same as the width of the limiting plate 4, which means that the limiting plate 4 can be better inserted into the U-shaped clamping frame 61 and be firmly fixed;

[0046] The combination of the U-shaped bolt frame 61 and the fastening screw 62 provides a reliable fixing point for the limiting plate 4, which not only ensures the stability of the limiting plate 4 in the vertical direction, but also prevents its movement or deviation in the horizontal direction;

[0047] By rotating the fastening screw 62, the worker can easily fix or release the limiting plate 4, which not only simplifies the installation and disassembly process, but also improves work efficiency.

[0052] In use, first, the round pad plate 1 is stably placed in the working area, then according to the different length batch of elevator compensation chain, the appropriate threaded stud 21 and positioning column 2 combination body are selected, and they are fixed in the screw hole 12 in the center of the round pad plate 1 by screwing;

[0053] Then, select the appropriate limiting plate 4, after the limiting plate 4 is placed vertically on the ground, its top surface needs to be flush with the top surface of the positioning column 2, so as to ensure that the compensation chain can keep horizontal and will not exceed the predetermined range during the winding and stacking process;

[0054] Next, according to the height to be stacked and the radius of winding, adjust the sliding position of the plug-in plate 3 in the slot 11, at the same time, according to the length of the plug-in plate 3 extending radially outward, select the appropriate round gasket 5 to be concentrically connected outside the round pad plate 1, so as to ensure the stability and balance of the whole tooling structure.

[0055] By rotating the fastening screw 62 in the U-shaped bolt frame 61 of the bolt fastening part 6, the bottom of the limiting plate 4 is vertically inserted into the U-shaped bolt frame 61 and tightly fixed, so as to ensure the firm connection between the limiting plate 4 and the plug-in plate 3;

[0056] Finally, the elevator compensation chain is placed in the area surrounded by the positioning column 2 and the limiting plate 4, and the winding and stacking operation is performed; due to the stability and limiting effect of the tool structure, the compensation chain can be kept horizontal and will not be skewed or collapsed, thereby improving the winding efficiency and product quality.

[0057] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
