Description

Technical Field

[0001] The utility model relates to a counterweight device, in particular to a counterweight device containing a tenonless counterweight block. Background Art

[0002] The counterweight device of an elevator is a device that runs relative to the car in the elevator. The counterweight and the car move up and down relatively during the traction work, playing a role in balancing the load and effectively reducing the traction force required by the traction machine. As Figure 1 shown, the traditional counterweight device includes a counterweight frame 1-1 and counterweight blocks 1-2 installed on the counterweight frame 1-1. Multiple counterweight blocks 1-2 in the counterweight frame 1-1 are used to adjust the overall load weight of the counterweight device, so as to adjust the load capacity of the elevator car. The counterweight frame 1-1 includes a counterweight upper beam, a counterweight lower beam and counterweight vertical beams. Tenons are provided on both sides of the counterweight block 1-2. When installing the counterweight block 1-2, the tenons of the counterweight block 1-2 need to be stuck in the grooves of the counterweight vertical beams, so as to play a role in fixing the counterweight block 1-2. However, the structure of such a counterweight block 1-2 makes the total length of the counterweight block 1-2 including the tenons greater than the distance between the counterweight vertical beams. During installation, it needs to be placed obliquely. The installation method is troublesome and takes up a large space, which will lead to a reduction in the number of installed counterweight blocks 1-2. If it is necessary to increase the number of counterweight blocks 1-2, the height of the counterweight device needs to be increased, which requires a high wellbore space and increases the cost. Content of the Utility Model

[0003] The purpose of the utility model is to provide a counterweight device containing a tenonless counterweight block.

[0004] The utility model has the characteristic of reducing the height of the counterweight device.

[0023] Embodiment:

[0024] As Figures 2-6 shown, a counterweight device with a tenonless counterweight block includes a counterweight frame 1. A plurality of first counterweight blocks 2 and at least two second counterweight blocks 3 located at the uppermost part are provided on the counterweight frame 1. Tenons 21 for cooperating with and clamping to the counterweight frame 1 are provided on both end faces of the first counterweight block 2. Grooves 31 are provided on both sides of the top surface of the second counterweight block 3, and a fixing assembly 4 connected to the counterweight frame 1 is provided on the grooves 31.

[0025] Preferably, three to five second counterweight blocks 3 are provided. Tenons 21 are not designed on both sides of the second counterweight block 3, so that the length of the second counterweight block 3 is less than the distance between two vertical beams 13. When installing, it is not necessary to tilt and place it, which is convenient for operation and installation; moreover, the installation occupies a small space, and the upper space of the counterweight device can be fully utilized, which can not only increase the installation quantity of the counterweight blocks, but also reduce the height of the counterweight frame 1 and reduce the cost. The second counterweight block 3 is connected to the counterweight frame 1 through the fixing assembly 4. By using the grooves 31 on the second counterweight block 3, the fixing assembly 4 is positioned and restricted, thereby improving the installation stability and accuracy of the fixing assembly 4 for the second counterweight block 3.

[0026] The counterweight frame 1 includes an upper beam 11, a lower beam 12, and U-shaped vertical beams 13. The U-shaped openings of the two vertical beams 13 face each other, and the tenons 21 are embedded in the U-shaped openings of the vertical beams 13.

[0027] The fixed component 4 includes a pressing plate 41 embedded in the groove 31. On one side of the pressing plate 41 facing the vertical beam 13, there is an extension plate 42 extending into the U-shaped opening of the vertical beam 13. On both the front and rear sides of the pressing plate 41, there are vertical plates 46 covering both sides of the second counterweight 3. A side plate 43 is provided on the extension plate 42, and a long circular hole 44 for the bolt 45 to pass through is provided on the side plate 43. The fixed component 4 is clamped on the second counterweight 3 through the cooperation of the pressing plate 41 and the groove 31, and the position of the second counterweight 3 is stabilized by the vertical plates 46. It is connected to the vertical beam 13 through the bolt 45, so as to stably install the second counterweight 3 on the counterweight frame 1. The installation is stable, the occupied space is small, and the counterweight space is saved. The structure of the fixed component 4 is simple, the installation is firm, the disassembly is convenient, and the cost is low.

[0028] A reinforcing plate 47 is further provided on the extension plate 42. One side of the reinforcing plate 47 is connected to the extension plate 42, and the other side of the reinforcing plate 47 is connected to the side plate 43. The design of the reinforcing plate 47 improves the strength and stability of the fixed component 4.

[0029] The depth of the groove 31 is not less than the thickness of the pressing plate 41. The pressing plate 41 is embedded inside the groove 31 lower than the groove 31 or flush with the top surface of the groove 31, avoiding the pressing plate 41 protruding from the top of the groove 31, thereby increasing the contact area between the upper and lower adjacent second counterweights 3 and making the installation and use of the counterweights more stable.
