Description

Technical Field

[0001] This utility model belongs to the field of single hydraulic props, and in particular relates to a heightening device for single hydraulic props that can meet the needs of ultra-high section construction in tunnels. Background Technology

[0002] With the improvement of mine safety production, safety should be given priority in the adoption of various underground support systems. The existing single-unit temporary support systems during the original roadway excavation and maintenance process cannot meet the temporary support requirements of all roadways, which may affect the mine's safe production.

[0003] The existing single hydraulic props in a certain mine are 3.5 meters high, but now construction is being carried out in the tunnels at heights of 4-5 meters. Therefore, the existing single hydraulic props cannot meet the needs of ultra-high section construction, and purchasing single hydraulic props requires waiting, which greatly delays the construction time. Utility Model Content

[0004] The purpose of this invention is to provide a heightening device for single hydraulic props that can meet the needs of ultra-high tunnel construction, so as to solve the cost pressure and extended construction problems caused by the large-scale purchase of ultra-long single props by mines due to the need for ultra-high tunnels.

[0005] The present invention adopts the following technical solution: a heightening device for a single hydraulic prop that can meet the construction requirements of ultra-high sections of tunnels, comprising multiple single heightening units; The single-unit height-increasing unit includes: Supporting columns, installed vertically; A horizontal support plate is installed horizontally, located on the upper side of the supporting column, and is solidly connected to the supporting column; The single-unit fixing cylinder is a cylindrical structure with openings at both the top and bottom. It is located on the upper side of the horizontal support plate, with its lower end fixedly connected to the horizontal support plate and its upper end extending upward. The opening at its upper end allows the lower end of the single hydraulic prop to extend from top to bottom, thereby limiting the lower end of the single hydraulic prop. This allows the supporting column to raise the single hydraulic prop, thus meeting the requirements for ultra-high section construction in the tunnel.

[0006] The beneficial effects of this utility model are: This utility model, after field testing, can effectively solve the problem of the inability to use single-unit temporary support during the construction of ultra-high roadways, and avoids the cost pressure of mines purchasing a large number of ultra-long single units due to the need for ultra-high roadways, as well as the pressure of waiting beyond the deadline. This invention significantly reduces the pressure of procuring ultra-long monomers, and its manufacturing cost is low. This invention, by setting a positioning unit, allows multiple individual heightening units to be fixed on the positioning unit, thereby avoiding the problem of a single unit extending downwards into the tunnel floor under force. In addition, by setting a positioning insertion plate for the positioning unit, the force on the heightening device can be greatly improved. Attached Figure Description

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more. The term "orientation" in this utility model refers to the orientation of the utility model within the... Figure 1 Description of the state's progression.

[0011] This utility model discloses a heightening device for a single hydraulic prop that can meet the needs of ultra-high tunnel construction, such as... Figure 1 and Figure 2 As shown, it includes multiple individual height-increasing units.

[0012] The single-unit heightening unit includes: a supporting column 10, a horizontal support plate 11, and a single-unit fixing cylinder 12.

[0013] The supporting columns 10 are set vertically.

[0014] The horizontal support plate 11 is set horizontally, located on the upper side of the support column 10, and is solidly connected to the support column 10.

[0015] The single-unit fixing cylinder 12 is a cylindrical structure with openings at both the top and bottom. The single-unit fixing cylinder 12 is located on the upper side of the horizontal support plate 11. The lower end of the single-unit fixing cylinder 12 is fixedly connected to the horizontal support plate 11, and the upper end of the single-unit fixing cylinder 12 extends upward. The upper opening of the single-unit fixing cylinder 12 is used for the lower end of the single hydraulic prop to extend from top to bottom, so that the single-unit fixing cylinder 12 limits the lower end of the single hydraulic prop, thereby increasing the height of the single hydraulic prop by the supporting column 10, thus meeting the requirements of ultra-high section construction in the roadway.

[0016] This utility model also includes: multiple bearing plates 13, all of which are horizontally arranged. The upper side of the multiple bearing plates 13 is fixedly connected to the lower end of each corresponding bearing column 10. The lower end of the multiple bearing plates 13 is used to abut against the roadway floor, thereby increasing the force-bearing surface of the bearing column 10.

[0017] This utility model also includes: a positioning unit; the positioning unit includes: a horizontal force-bearing plate 14 and a positioning insertion plate 15.

[0018] The horizontal load-bearing plate 14 is set horizontally and laid on the ground of the tunnel; multiple bearing plates 13 are arranged in a straight line and evenly distributed on the upper side of the horizontal load-bearing plate 14, and the lower side of the multiple bearing plates 13 is fixedly connected to the horizontal load-bearing plate 14.

[0019] The positioning insertion plate 15 is vertically arranged and located on the lower side of the horizontal force plate 14, along the direction of the horizontal force plate 14. The upper end of the positioning insertion plate 15 is fixedly connected to the horizontal force plate 14, and the lower end of the positioning insertion plate 15 is used to insert downward below the roadway surface.

[0020] The method of using this utility model is as follows: The horizontal load-bearing plate 14 and the positioning insertion plate 15, which are fixed together, are laid in the superelevation section of the roadway. Then, multiple bearing plates 13 are evenly arranged on the upper side of the horizontal load-bearing plate 14 and the bearing plates 13 and the horizontal load-bearing plate 14 are fixed. Then, the bearing columns 10, horizontal support plates 11, and single fixing cylinders 12, which are fixed together, are placed on the upper side of each bearing plate 13 and fixed. Then, the single hydraulic prop is raised and supported. Example

[0021] The existing single hydraulic props in a certain mine are 3.5 meters high, but now construction is being carried out in the tunnels at heights of 4-5 meters. Therefore, the existing single hydraulic props cannot meet the needs of ultra-high section construction, and purchasing single hydraulic props requires waiting, which greatly delays the construction time.

[0022] By processing the height-increasing device of this utility model and using it, the cost of purchasing individual units is greatly reduced. Furthermore, the height-increasing device of this utility model is very simple to process, very inexpensive, and has a very good height-increasing effect.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
