Description

Technical Field

[0001] The present application relates to the technical field of mining engineering machinery, and in particular to a single hydraulic column moving device. Background Art

[0009] The square steel runway is fixed to the first single hydraulic column by a quick clamp to form a moving track for the second single hydraulic column;

[0010] The column roller is arranged on the square steel runway through a bearing, and the column roller slides along the square steel runway;

[0011] The second single hydraulic column is fixed to the column holding roller through the quick clamp. The second single hydraulic column is a movable single hydraulic column, and the second single hydraulic column is detachably connected to the column holding roller through the quick clamp.

[0012] In one example, the quick clamp includes a circular clamp body and round steel; wherein the round steel is fixedly connected to the circular clamp body.

[0023] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0024] The terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the order used in this manner can be interchanged where appropriate, such that the embodiments of the invention described herein can be practiced in orders other than those illustrated or described herein.

[0025] In addition, the terms "comprises" and "having" and any variations thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0026] This specification discloses a single hydraulic column moving device, which includes a top plate 101, a bottom plate 102, a first single hydraulic column 103, a quick clamp 104, a column roller 105, a square steel runway 106 and a second single hydraulic column 107.

[0027] The plurality of first single hydraulic columns 103 fix the top plate 101 on the top of the tunnel and fix the bottom plate 102 on the bottom of the tunnel; the first single hydraulic columns 103 play a supporting role;

[0028] The square steel runway 106 is fixed to the first single hydraulic column 103 through a quick clamp 104 to form a moving track for the second single hydraulic column 107;

[0029] The column roller 105 is arranged on the square steel runway 106 through a bearing, and the column roller 105 slides along the square steel runway 106;

[0030] The second single hydraulic column 107 is fixed to the column holding roller 105 through the quick clamp 104 . The second single hydraulic column 107 is a movable single hydraulic column, and the second single hydraulic column 107 is detachably connected to the column holding roller 105 through the quick clamp 104 .

[0031] In the above, the square steel runway can be made of light square steel 40*40mm, each square steel is 6m, and the middle of the joint can be connected with 6-branch pipes.

[0032] In one example, the quick clamp 104 includes a circular clamp body and a round steel 204 ; wherein the round steel 204 is fixedly connected to the circular clamp body.

[0033] At this time, the quick clamp can quickly hold the single hydraulic column, fix it firmly and easily disassemble it. It can be rotated along the wall of the single hydraulic column and fixed on the square steel runway through round steel.

[0034] In one example, the column roller 105 includes a groove 201, a bearing 203 and a bolt shaft 202; wherein, the groove 201 is welded from three steel plates, and four holes are punched on both sides of the groove 201; the four holes are divided into two groups of rollers, each group of rollers is installed with two bearings 203, and bolts are passed through the holes on both sides of the groove 201 and the two bearings to fix the two bearings 203 in the groove 201; the bolts fix the two bearings to form the bolt shaft 202.

[0035] In an example, the second single hydraulic column 107 is fixedly mounted on the column roller 105 through the round steel 204 of the quick clamp 104 .

[0036] In an example, the square steel runway 106 is fixedly mounted on the first single hydraulic column 103 through the round steel 204 of the quick clamp 104 .

[0037] Workers can easily move the single hydraulic column using the single hydraulic column moving device described in this manual. For example, each lane previously employed three workers, but now employs two, saving one worker per shift. Based on two production shifts per day, this saves four workers per day, resulting in an annual wage savings of approximately 4*30*260*10 = 312,000 yuan. This significantly reduces the incidence of work-related accidents, and the economic value is immeasurable.

[0038] The device in the present application has a simple structure, is easy to use, and has low cost, and can conveniently move a single hydraulic column.
