[0001] The utility model relates to the technical field of elevator accessory design, in particular to a counterweight connecting piece. Background Art

[0002] Counterweights are generally installed in an elevator shaft and are lifted in cooperation with an elevator car. Existing elevator counterweights are mainly composed of solid counterweights, and corresponding weight counterweights are carried out according to the weight requirements of the elevator.

[0003] As disclosed in the invention patent with the publication number CN106429757B and the name of an elevator counterweight, it includes a counterweight frame, counterweights are arranged on the counterweight frame, the counterweights are successively provided with a top counterweight, a middle counterweight and a bottom counterweight from top to bottom, and several middle counterweights are provided.

[0004] As described in the above patent, during actual installation, the counterweight plates are generally stacked and placed on the counterweight frame and then fixed. This installation method easily causes the counterweights to shake and rub against each other during use, reducing the service life of the counterweights, and in the long run, it easily causes the components originally fixing the counterweights to become loose, posing a safety hazard. Content of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the utility model provides a counterweight connecting piece for solving the technical problem in the background art that existing counterweights are prone to shaking and may pose a safety hazard during use after installation.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A counterweight connecting piece includes a plate body, several through holes for a cable to pass through are arranged on the plate body, connecting plates integrally cut and bent are respectively arranged on two opposite sides of the plate body, and the two connecting plates are used for clamping the side walls of the upper and lower counterweights of the plate body. Upper limit pieces for limiting the counterweight above the plate body and lower limit pieces for limiting the counterweight below the plate body are respectively arranged on the other two opposite sides of the plate body.

[0008] Working Principle:

[0009] This application is a counterweight connecting piece, mainly used for placing between every two counterweights during the installation of counterweights and limiting the upper and lower two counterweights.

[0010] During use, the plate body is placed on the counterweight frame and between every two counterweights. When the counterweight is placed above or below the plate body, the two sides of the counterweight are clamped by the connecting plates.

[0011] Further limit the counterweight located above the plate body through the upper limit member, and limit the counterweight below the plate body through the lower limit member, and it can be completed after installation.

[0012] Beneficial effects obtained:

[0013] First, there is a connecting plate formed by integral cutting and bending. The connection strength between the connecting plate and the plate body is effectively improved through integral bending. The connecting plate can effectively limit the horizontal lateral position of the counterweight and prevent the lateral position of the counterweight from shaking.

[0014] Second, there are upper limit members and lower limit members. The upper limit member can effectively limit the horizontal longitudinal position of the counterweight located above the plate body, and the lower limit member can effectively limit the horizontal longitudinal position of the counterweight located below the plate body, preventing the counterweight located above or below the plate body from shaking in position.

[0015] Third, through the arranged plate body, the situation of friction between counterweights can be effectively solved. Description of the drawings

[0023] Embodiment:

[0024] Refer toFigures 1 to 5 This application relates to a counterweight connecting piece, which includes a plate body 1. Anti-slip strips 14 are provided on both the top and bottom of the plate body 1. The anti-slip strips 14 can be made of rubber material, effectively preventing the counterweight 18 from sliding on the plate body 1. A number of through holes 2 for the cable to pass through are provided on the plate body 1. The through holes 2 correspond one by one to the holes on the counterweight 18 and are used for the cable of the traction device to pass through. Connecting plates 3 formed by integral cutting and bending are respectively provided on the opposite sides of the plate body 1. The two connecting plates 3 are used to be clamped with the side walls of the upper and lower counterweights 18 of the plate body 1. A convex strip 12 is provided at the end of each connecting plate 3 away from the plate body 1. The connecting plate 3 is clamped with the clamping groove 19 on the counterweight 18 through the convex strip 12. A buffer layer 13 is provided on one side of each connecting plate 3 facing the counterweight 18. The buffer layer 13 is made of rubber material and is used to abut against the side wall of the counterweight 18. A threaded hole 17 is provided on the side of each connecting plate 3 facing away from the plate body 1. The provided threaded hole 17 facilitates the connection and positioning of the plate body 1 through the threaded hole 17 when it needs to be installed on the counterweight frame, making the plate body 1 more stable during use.

[0025] As Figure 2 and Figure 3 shown, upper limit members for limiting the upper counterweight 18 above the plate body 1 are respectively provided on the other two opposite sides of the plate body 1. There are two upper limit members and they are arranged oppositely on the plate body 1. The upper limit member includes an upper rotating rod 4, an upper limit plate 5, a first torsion spring 6 and an upper protrusion 7. The upper rotating rod 4 is rotatably arranged on the side wall of the plate body 1. The upper limit plate 5 is fixedly arranged on the upper rotating rod 4. The first torsion spring 6 is sleeved on the upper rotating rod 4. One end of the first torsion spring 6 is fixedly connected to the plate body 1, and the other end of the first torsion spring 6 is fixedly connected to the upper limit plate 5. The upper protrusion 7 is fixedly arranged at the end of the upper limit plate 5 away from the upper rotating rod 4, and the upper protrusion 7 is used to be clamped with the clamping groove 19 on the counterweight 18. The upper limit plate 5 makes the upper protrusion 7 always remain in the clamping groove 19 on the upper counterweight 18 above the plate body 1 through the resilience of the first torsion spring 6 to achieve the clamping effect.

[0026] As Figure 4 and Figure 5As shown in the figure, it further includes a lower limit member for limiting the counterweight 18 below the plate body 1. There are two lower limit members and they are oppositely arranged on the plate body 1. The lower limit member includes a lower rotating rod 8, a lower limit plate 9, a second torsion spring 10 and a lower protrusion 11. The lower rotating rod 8 is rotatably arranged on the side wall of the plate body 1, the lower limit plate 9 is fixedly arranged on the lower rotating rod 8, the second torsion spring 10 is sleeved on the lower rotating rod 8, one end of the second torsion spring 10 is fixedly connected with the plate body 1, the other end of the second torsion spring 10 is fixedly connected with the lower limit plate 9, the lower protrusion 11 is fixedly arranged at one end of the lower limit plate 9 away from the lower rotating rod 8, and the lower protrusion 11 is used for clamping with the counterweight 18. The lower limit plate 9 makes the lower protrusion 11 always clamped in the clamping groove 19 on the counterweight 18 below the plate body 1 through the resilience of the second torsion spring 10. Avoidance grooves 15 are provided on several upper limit plates 5 and several lower limit plates 9. By providing the avoidance grooves 15, the upper protrusion 7 or the lower protrusion 11 can extend more into the clamping groove 19 on the corresponding counterweight 18, improving the clamping effect. Several upper limit plates 5 and several lower limit plates 9 are both provided with handles 16, and through the handles 16, it is convenient for the installer to move the upper limit plate 5 or the lower limit plate 9.

[0027] Working principle:

[0028] When in use, place the plate body 1 on the counterweight frame and place it between every two counterweights 18. When the counterweight 18 is placed above or below the plate body 1, the convex strips 12 on the connecting plate 3 extend into the clamping grooves 19 on both sides of the counterweight 18 to achieve clamping. Because the connecting plate 3 has a certain elasticity, the convex strips 12 can be clamped into the clamping grooves 19 by directly squeezing the side wall of the corresponding block, or by pulling one side of the upper limit plate 5 or the lower limit plate 9 and aligning the clamping groove 19 on the side wall of the counterweight 18 with the convex strips 12, and then pushing the counterweight 18 to complete the installation. The upper limit plate 5 or the lower limit plate 9 is pulled to limit the counterweight 18 above or below the plate body 1, and the upper protrusion 7 and the lower protrusion 11 are always clamped in the clamping groove 19 of the counterweight 18 through the first torsion spring 6 and the second torsion spring 10, and then the installation is completed.
