Description

Technical Field

[0001] This utility model relates to the technical field of crusher hoisting, and in particular to a crusher jaw plate hoisting device. Background Technology

[0002] The jaw plate is a crucial component of a jaw crusher, typically made of highly wear-resistant materials. Crusher jaw plates are divided into fixed jaw plates and movable jaw plates. The fixed jaw plate is fixedly mounted on the crusher frame; the movable jaw plate is connected to the crusher's drive mechanism. The crusher's drive mechanism acts on the movable jaw plate, causing it to reciprocate and continuously compress against the fixed jaw plate to complete the crushing task. The jaw plate is generally rectangular or trapezoidal; one side of the jaw plate has evenly distributed teeth to increase the friction between the material and the jaw plate, ensuring the crushing effect of the jaw crusher. The top of the jaw plate has a through-hole inverted trapezoidal groove; the jaw crusher has mounting posts that correspond to and match the inverted trapezoidal groove. The mounting posts are inserted into the inverted trapezoidal groove to connect the jaw plate to the jaw crusher. Existing lifting tools, including slings and wire ropes, are unsuitable for lifting crusher jaw plates. When using slings to lift the jaw plate, the teeth easily wear down the slings; when using wire ropes, the jaw plate easily slips. Existing technologies lack lifting devices for crusher jaw plates.

[0023] Example 1: See Figure 1-3 A jaw plate hoisting device for a crusher includes an L-shaped clamping plate 1 and a lifting ring 2. The clamping plate 1 is used to clamp the jaw plate of the crusher. The lifting ring 2 provides a stable lifting point for the clamping plate 1. The clamping plate 1 includes a vertical plate 11 and a horizontal inverted trapezoidal block 12. The inverted trapezoidal block 12 matches and corresponds to the inverted trapezoidal groove 03 of the crusher jaw plate. The inverted trapezoidal block 12 is inserted into the inverted trapezoidal groove 03 to achieve a direct connection between the clamping plate 1 and the crusher jaw plate. The upper end of the vertical plate 11 is aligned with the inverted trapezoidal block 12. The end is fixed, and the lower end extends beyond the inverted trapezoidal groove 03 of the crusher jaw plate; a lifting ring 2 is installed above the inverted trapezoidal block 12; the lifting ring 2 can lift the inverted trapezoidal block 12; the inverted trapezoidal block 12 drives the crusher jaw plate to rise together through the inverted trapezoidal groove 03; the friction between the inverted trapezoidal block 12 and the inverted trapezoidal groove 03 can ensure that the clamping plate 1 does not come out of the inverted trapezoidal groove 03 as much as possible; the lower end of the vertical plate 11 abuts against the crusher jaw plate to assist in lifting the crusher jaw plate.

[0024] Compared with the prior art, this utility model provides a lifting device that can use the inverted trapezoidal groove 03 of the jaw plate of a crusher for lifting. It has a simple structure and is easy to operate.

[0025] The clamping plate component 1 also includes a clamping plate 13 and a connecting screw 14; the clamping plate 13 and the vertical plate 11 are respectively set at both ends of the inverted trapezoidal block 12; the clamping plate 13 and the vertical plate 11 are of similar length; the upper end of the clamping plate 13 is detachably connected to the inverted trapezoidal block 12 through the connecting screw 14; the clamping plate 13 and the vertical plate 11 cooperate with each other to achieve more complete limiting of the jaw plate of the crusher.

[0026] There are several connecting screws 14 to increase the connection strength between the locking plate 13 and the inverted trapezoidal block 12; in this embodiment, there are 2 connecting screws 14.

[0027] The clamping plate 1 also includes a horizontal plate 15; the horizontal plate 15 is fixed above the inverted trapezoidal block 12; the horizontal plate 15 provides an operating end for operating the clamping plate 1, so as to facilitate connection with the crusher jaw plate on site.

[0028] The bottom edge of the inverted trapezoid is provided with rounded corners 121 so that the inverted trapezoidal block 12 can be smoothly inserted into the inverted trapezoidal groove 03 of the crusher jaw plate.

[0029] The inclined surfaces on both sides of the inverted trapezoidal block 12 match the inclined inner wall of the inverted trapezoidal groove 03; the cross-sectional area of ​​the inverted trapezoidal block 12 is less than the cross-sectional area of ​​the inverted trapezoidal groove 03, so that the inverted trapezoidal block 12 can be inserted into the inverted trapezoidal groove 03.

[0030] The lifting ring 2 uses a lifting ring 2 bolt and is threadedly connected to the horizontal block; compared with the jaw plate of the crusher, the machining difficulty of the horizontal plate 15 is greatly reduced, and it can be detachably connected to the lifting ring 2 bolt; the lifting ring 2 can be replaced, which is convenient for maintenance.

[0031] Both the fixed jaw plate 01 and the movable jaw plate 02 on the jaw crusher are equipped with teeth, and the teeth of the fixed jaw plate 01 and the movable jaw plate 02 are staggered. In order to enable the jaw plate hoisting device of this invention to hoist both the fixed jaw plate 01 and the movable jaw plate 02, the lower end of the vertical plate 11 and the lower end of the positioning plate 13 are both flat plates.

[0032] The working process of this embodiment is as follows: Remove the connecting screw 14 to separate the locking plate 13 from the inverted trapezoidal block 12; insert the inverted trapezoidal block 12 into the inverted trapezoidal groove 03; step on the lower end of the vertical plate 11 so that the vertical plate 11 is close to the jaw plate of the jaw crusher; use a crane to lift the lifting ring 2; after the wire rope is tightened, it can be ensured that the inverted trapezoidal block 12 is close to the inner wall of the inverted trapezoidal groove 03; continue to lift the lifting ring 2 and lift the jaw plate of the crusher by side pulling; connect the locking plate 13 and the inverted trapezoidal block 12 by connecting screw 14; continue to lift the jaw plate of the crusher.

[0033] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that the length of the inverted trapezoidal block 12 is equivalent to the thickness of the crusher jaw plate, which can improve the stability of the crusher jaw plate during hoisting.
