Description

Technical Field

[0001] The utility model relates to the technical field of jaw crushers, in particular to a jaw crusher with a floorless bolt installation method. Background Technique

[0002] A jaw crusher consists of a moving jaw and a static jaw, and the two jaw plates form a crushing cavity. It is a crusher that simulates the movement of the two jaws of an animal to complete the material crushing operation. It is widely used in various industries such as mining and smelting, building materials, highways, railways, water conservancy, and chemical industries for the crushing of various ores and large pieces of materials.

[0003] Most of the existing jaw crushers are fixed to the ground through floor bolts. During crushing, the floor bolts bear a large shear stress, which easily causes the bolts to break, or the nuts become loose due to machine load vibration or the decay of the shock-absorbing wooden boards in the pit, and ultimately the floor bolts break. The repair process is cumbersome, seriously affecting the crushing progress. Moreover, for short-term temporary crushing work, using floor bolts for fixation is not only time-consuming and laborious, but also requires the removal of floor bolts after the crushing work is completed, further increasing the labor and time costs. Therefore, we propose a jaw crusher with a floorless bolt installation method. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a jaw crusher with a floorless bolt installation method, which does not require pre-burying floor bolts in advance nor removing floor bolts, is simple to operate, convenient to use, time-saving and labor-saving, and greatly improves the work efficiency, and can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A jaw crusher with a floorless bolt installation method, including a crusher main body. On the outer sides of both surfaces of the crusher main body, two counterweight boxes are symmetrically arranged. The upper surface of the counterweight box is open, and a first shock-absorbing pad is arranged on the lower surface of the counterweight box. A second shock-absorbing pad is arranged on the lower surface of the crusher main body.

[0006] As a preferred technical scheme of the utility model, at least one side surface of the counterweight box that is not connected to the crusher main body is provided with an opening, and a hinged plate is hinged at the opening.

[0007] As a preferred technical scheme of the utility model, two clamping columns are symmetrically and fixedly arranged on both sides of the side surface of the hinged plate. On the side plate of the counterweight box provided with the hinged plate, two rotating plates are symmetrically and rotatably arranged. A clamping groove is arranged on the side surface of the rotating plate, and the rotating plate clamps the clamping column through the clamping groove.

[0008] As a preferred technical scheme of the utility model, a circular limiting plate is fixedly arranged on the outer side surface of the end of the clamping column, and the diameter of the limiting plate is larger than the diameter of the clamping groove.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3, the present utility model provides a technical solution: a jaw crusher with a floorless bolt installation method, including a crusher main body 1. On the outer sides of the two surfaces of the crusher main body 1, two counterweight boxes 2 are symmetrically arranged. The upper surface of the counterweight box 2 is open for placing a counterweight device. After moving the crusher to a temporary site where it needs to work for a short time, counterweight blocks are placed in the counterweight box 2, or materials with a relatively high density on-site, such as crushed stones, are put into the counterweight box 2, which can achieve the effect of counterweight fixation and prevent the crusher from shifting during operation.

[0018] A first shock-absorbing pad 11 is arranged on the lower surface of the counterweight box 2, and a second shock-absorbing pad 12 is arranged on the lower surface of the crusher main body 1. In cooperation with the first shock-absorbing pad 11 under the counterweight box 2 and the second shock-absorbing pad 12 under the crusher main body 1, it can play a role in shock absorption, anti-slip, and increasing stability, enabling the crusher to complete the crushing work normally. After the crushing work is completed, the counterweight blocks or materials used for counterweight are taken out, and then the crusher can be transferred to the next temporary site. There is no need to pre-embed floor bolts in advance or remove floor bolts. The operation is simple, convenient to use, time-saving and labor-saving, and greatly improves work efficiency.

[0019] In a preferred technical solution, at least one side of the counterweight box 2 that is not connected to the crusher main body 1 is provided with an opening, and a hinged plate 3 is hinged at the opening. When placing crushed stones for counterweight in the counterweight box 2, the crushed stones can be quickly discharged by opening the hinged plate 3, facilitating the quick transfer of the crusher; when pouring concrete into the counterweight box 2 for counterweight, the hinged plate 3 can be opened to facilitate the demolding of the concrete blocks in the counterweight box 2.

[0020] In a further preferred technical solution, two clamping columns 6 are symmetrically and fixedly arranged on both sides of the side surface of the hinged plate 3. Two rotating plates 4 are symmetrically and rotatably arranged on the side plate of the counterweight box 2 where the hinged plate 3 is located. A clamping groove 5 is opened on the side surface of the rotating plate 4, and the rotating plate 4 clamps the clamping column 6 through the clamping groove 5, thereby fixing the hinged plate 3 through the rotating plate 4 to close the counterweight box 2 and prevent the internal counterweight material from pushing open the hinged plate 3.

[0021] Furthermore, a circular limiting plate 7 is fixedly arranged on the outer side surface of the end of the clamping column 6. The diameter of the limiting plate 7 is larger than the diameter of the clamping groove 5. The rotating plate 4 is limited by the limiting plate 7 to prevent it from deflecting and disengaging from the clamping column 6. At the same time, it can also assist the rotating plate 4 to fix the hinged plate 3 and ensure the normal use of the counterweight box 2.

[0022] In a preferred technical solution, a number of groups of mounting blocks 8 are symmetrically and fixedly arranged on both side surfaces of the counterweight box 2. An installation hole 9 is formed on the side surface of the mounting block 8, and an installation screw hole corresponding to the position of the installation hole 9 is formed on the outer surface of the crusher main body 1. The counterweight box 2 can be installed on the crusher main body 1 by passing an installation bolt through the installation hole 9 and screwing it into the installation screw hole, so as to reduce the floor area of the crusher main body 1 when the crusher needs to be transported and transferred, improve the transportation effect, and at the same time facilitate the replacement of the worn or damaged counterweight box 2.

[0023] In a preferred technical solution, screw holes are formed at the four corners of the lower surface of the counterweight box 2. A screw rod is threadedly connected in the screw hole, and an adjusting anchor 10 is fixedly arranged at the bottom end of the screw rod. By rotating the screw rod, the height of the adjusting anchor 10 can be adjusted, so as to adjust the height of the counterweight box 2, which is applicable to a temporary working place with poor ground flatness.

[0024] The present application also provides another embodiment, which is substantially the same as the above embodiment, except that: a number of through holes are uniformly formed on the bottom plate of the counterweight box 2, and a pit corresponding to the position of the counterweight box 2 is formed at the working place of the crusher. After the position of the crusher is fixed, concrete is poured into the counterweight box 2, so that the concrete passes through the through holes and is injected into the pit. Finally, the concrete in the pit and the concrete in the counterweight box form an integral body. The advantage is that the fixation is more firm, and the crusher can work stably for a longer time, which is applicable to a temporary working place that needs to work for a long time (more than one week); the disadvantage is that the demoulding is troublesome. It is necessary to first disassemble the crusher main body 1 and the counterweight box 2, then crush the concrete by a road crusher, etc., and then separate the counterweight box 2 from the concrete and demould it, etc. Therefore, it is applicable to a temporary working place that needs to work for a long time (more than one week). Steel bars can also be inserted into the through holes during the pouring of concrete to further improve the connection firmness.

[0025] The parts not disclosed in the present utility model are all prior arts, and their specific structures, materials and working principles will not be elaborated. Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
