[0024] REFERENCE Figure 1The utility model provides an embodiment: an elevator counterweight balance device convenient to installation, including device body 1, both ends of device body 1 are fixedly connected with two mounting blocks 2, and the top side of mounting block 2 is equipped with the positioning hole, and the positioning hole penetrates the inside of mounting block 2, and the both sides of device body 1 are connected with fixed frame 5 through connecting plate 10, and the bottom side of device body 1 is connected with bottom plate 7 through support block 18, and the top side of device body 1 is fixedly connected with a plurality of mounting plates 4, and the inside of device body 1 is screwly connected with two screw rods 3, and the inside of device body 1 is slidably connected with a plurality of counterweight blocks 8, and the inner wall of counterweight block 8 is screwly connected on the outer wall of screw rod 3. Limiting hole 15 penetrates the inside of connecting block 10, and the inner wall of limiting hole 15 is slidably connected on the outer wall of limiting column 9. The top side of two support blocks 18 is in contact with the bottom side of device body 1, and spring two 17 one end is connected with the bottom side of support block 18, and the other end is connected with the inside bottom end of fixed column 16. The inside of two fixed frame 5 is fixedly connected with slide rod 12, and the outer wall of two slide rod 12 is equipped with spring one 13, and the top side and bottom side of mounting block 2 are slidably connected with limiting column 14, and the apart one end of two limiting column 14 is fixedly connected with moving plate 11. The inside of two moving plate 11 of middle end is slidably connected on the outer wall of slide rod 12. The both ends of spring one 13 are connected with the apart one side of two moving plate 11 of middle end respectively.
[0025] Specifically, when installing the elevator counterweight balance device, the operator first needs to preliminarily connect the fixed frame and the device body. The limiting columns 14 on the top end and the bottom end moving plates 11 of the fixed frame 5 are aligned with the mounting blocks 2 on the two sides of the device body 1 and are clamped. After completing the preliminary clamping, the two moving plates 11 in the middle are adjusted. The two moving plates 11 are sleeved on the slide rods 12 inside the fixed frame 5, and the spring one 13 on the outer wall of the slide rod 12 is connected to the apart one side of the two moving plates 11 in the middle. At this time, the operator pulls one of the moving plates 11 in the middle, utilizes the force deformation characteristics of the spring one 13, and makes the two moving plates 11 closer to the middle, clamps one of the moving plates 11 with the bottom end of the mounting block 2, and thereby forms the clamping state of the two moving plates 11 to one mounting block 2.
[0026] Referring to Figure 2 The front and rear sides of the fixed frame 5 are fixedly connected with the fixed blocks 6, the proximal ends of the two fixed blocks 6 are rotatably connected with the connecting blocks 10, the front side of the connecting block 10 is provided with the limiting hole 15, and the top end and the bottom end of the device body 1 are fixedly connected with the limiting columns 9.
[0027] Specifically, the connecting blocks 10 on the fixed blocks 6 on the front and rear sides of the fixed frame 5 are rotated, the limiting hole 15 in the connecting block 10 is clamped with the limiting column 9 on the device body 1, and thereby the fixing and limiting of the overall position of the fixed frame 5 are realized.
[0028] Referring to Figure 3The bottom plate 7 is fixedly connected with two fixed columns 16 on the top side, and the two fixed columns 16 are slidably connected with supporting blocks 18 inside.
[0029] Specifically, the supporting blocks 18 are slidably connected inside the fixed columns 16 fixedly connected on the top side of the bottom plate 7, and the top side of the supporting blocks 18 is tightly attached to the bottom side of the device body 1. When the device body 1 is impacted, the impact force will be transmitted to the supporting blocks 18 through the device body 1, and at this time, the spring two 17 inside the fixed column 16 will absorb the impact force and deform, thereby buffering the device as a whole and preventing the device from being damaged.
[0030] Working principle: When the operator installs the elevator centering and balancing device, first, the positioning columns 14 on the moving plates 11 at the top and bottom ends of the fixed frame 5 are clamped with the mounting blocks 2 on both sides of the device body 1, and after clamping is completed, the two moving plates 11 at the middle end of the fixed frame 5 are pulled, and the two moving plates 11 at the middle end slide on the outer wall of the fixed slide rod 12 inside the fixed frame 5, and the outer wall of the fixed slide rod 12 is provided with a spring one 13, and the two ends of the spring one 13 are connected with the sides away from each other of the two moving plates 11 at the middle end. Under the characteristics of the spring one 13 itself being stressed and deformed, one of the moving plates 11 at the middle end is pulled to be clamped with the bottom end of the mounting block 2, forming the effect of clamping one mounting block 2 with two moving plates 11. After clamping and clamping are completed, the connecting blocks 10 on the fixed blocks 6 on the front and rear sides of the fixed frame 5 are rotated to make the limiting holes 15 inside the connecting blocks 10 clamped with the limiting columns 9 on the device body 1, realizing the fixation and limiting of the overall position of the fixed frame 5. The bottom end of the device body 1 is provided with a buffer mechanism, the bottom plate 7 provided at the bottom end of the device body 1 is fixedly connected with the fixed columns 16 on the top side, the supporting blocks 18 are slidably connected inside the fixed columns 16, and the top side of the supporting blocks 18 is tightly attached to the bottom side of the device body 1. At the same time, a spring is arranged inside the fixed column 16. When the device body 1 as a whole is impacted, the force will be transmitted to the supporting blocks 18 through the device body 1, the spring two 17 arranged inside the fixed column 16 absorbs the force and deforms, buffers the device as a whole, and avoids damage to the device.
