Description

Technical Field

[0001] This utility model relates to the field of downhole support, and in particular to a modular quick-installation temporary support. Background Technology

[0002] Sudden geological risks such as roof falls and rockfalls are common in underground roadways, often forcing work interruptions. In such situations, rapid deployment of temporary supports and swift risk mitigation are crucial. While traditional temporary supports can provide necessary support, their bulky structure and complex installation often hinder rapid deployment. In emergencies, delays in the installation of traditional supports prolong roof exposure time, exacerbating the risk of surrounding rock loosening and collapse, severely impacting construction safety. Furthermore, these supports typically employ a monolithic steel structure design, making transportation difficult and requiring hoisting with tunnel boring machines or cranes, resulting in cumbersome procedures. In space-constrained roadways, the massive support components are difficult to move quickly, often requiring repeated adjustments by installation personnel, further wasting time. These limitations render existing temporary supports inadequate for meeting the demands of rapid underground support, necessitating design improvements to enhance installation efficiency and adaptability. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a modular quick-assembly temporary support with a simple structure, modular support, easy manual handling and quick assembly.

[0004] The device includes a column shoe unit, which includes two column shoe units. Each pair of column shoe units forms a group. Nested positioning tubes are provided on the two column shoe units in a group, and positioning pins are provided on the positioning tubes. Each column shoe unit is equipped with a hydraulic column support; a positioning groove and a positioning block are also provided between each hydraulic column support and its corresponding column shoe unit. The piston of the hydraulic single prop is provided with an assembly base, that is, the pistons of the two hydraulic single props in the column shoe unit are respectively provided with assembly bases; the two assembly bases are respectively fitted with assembly parts, and the assembly parts are fixedly provided with support beams, and the assembly parts are provided on both sides of the bottom surface of the support beams.

[0005] The effect achieved is that, based on the slot connection and positioning pin locking between the two column shoe units in the column shoe unit, the relative distance between the two column shoes can be quickly determined; based on the setting of positioning groove and positioning block, the hydraulic single prop can quickly position the orientation within the column shoe unit, thereby realizing the positioning of the spacing and orientation between the two assembly bases; under this condition, the support beam can be quickly assembled; after the assembly is completed, the hydraulic single prop moves to push the support beam towards the roadway top, realizing the support positioning. By sequentially arranging multiple sets of this equipment in the roadway, the temporary support frame in the roadway can be quickly arranged, and this can be used as the support foundation for temporary emergency construction.

[0006] The beneficial effects of this utility model are: it solves the problem of difficult assembly and transportation of temporary support structures in the prior art, and realizes the rapid assembly and use of temporary supports under special working conditions. Its structure is simple, assembly is fast and efficient, and its modular design allows for manual handling and rapid emergency response.

Detailed Implementation

[0008] Reference Figure 1 , Figure 2 The present invention provides a modular quick-installation temporary support, which includes a column shoe unit. The column shoe unit includes two column shoe units 4, and each pair of column shoe units 4 forms a group. The two column shoe units 4 in a group are provided with nested positioning tubes 5, and the positioning tubes 5 are provided with positioning pins. Each of the column shoe units 4 is provided with a hydraulic unit support 3; a positioning groove and a positioning block are also provided between each hydraulic unit support 3 and its corresponding column shoe unit 4. The piston of the hydraulic single support 3 is provided with an assembly base 31, that is, the pistons of the two hydraulic single support 3s in the column shoe unit are respectively provided with assembly bases 31; the two assembly bases 31 are respectively fitted with an assembly kit 2, and the support beam 1 is fixedly installed on the assembly kit 2, and the assembly kit 2 is located on both sides of the bottom surface of the support beam 1.

[0009] The effect achieved is that, based on the slot connection and positioning pin locking between the two column shoe units 4 in the column shoe unit, the relative distance between the two column shoes can be quickly positioned; based on the setting of positioning groove and positioning block, the hydraulic single support 3 can quickly position the orientation within the column shoe unit 4, thereby realizing the positioning of the distance and orientation between the two assembly bases 31; under this condition, the support beam 1 can be quickly assembled; after the assembly is completed, the hydraulic single support 3 moves to push the support beam 1 towards the top of the roadway, realizing the support positioning. By sequentially arranging multiple sets of this equipment in the roadway, the temporary support frame in the roadway can be quickly arranged, and this can be used as the support foundation for temporary emergency construction.

[0010] Example 1: The column shoe includes a base plate, and a positioning sleeve is provided on the base plate. The positioning sleeve is a circular sleeve in the form of a sleeve corresponding to the lower outer diameter of the hydraulic single support column 3. A reinforcing rib 12 is also provided between the base plate and the positioning sleeve.

[0011] The effect achieved in this way is to improve the stability of equipment layout.

[0012] Furthermore, the positioning tube 5 is set on the side of the base plate. The positioning tube 5 on the two individual column shoes 4 in each group of column shoes is a tube-sleeve structure, that is, the positioning tube 5 on one individual column shoe 4 is an inner sleeve, and the sleeve on the other individual column shoe 4 is an outer sleeve. The positioning pin is located between the inner and outer sleeves.

[0013] Furthermore, the inner and outer tubes are square tubes or spline tubes; The positioning pin is a spring pin set on the inner sleeve, and a pin hole is provided on the outer sleeve.

[0014] This achieves the effect of quickly positioning and locking the two individual pillar shoe units 4 in the pillar shoe unit.

[0015] In Example 2, the assembly base 31 is fixedly mounted on the piston of the hydraulic unit support 3, and a positioning block is provided on it.

[0016] Furthermore, the positioning block is composed of multiple positioning rods, and the bottom surface of the assembly 2 is provided with assembly slots corresponding to the positioning rods.

[0017] This achieves the effect of accurate positioning between the support beam 1 and the hydraulic single prop 3.

[0018] In Example 3, the support beam 1 includes a bottom crossbeam 13, and the mounting bracket 2 is disposed below the bottom crossbeam 13; A curved support beam 11 is integrally connected to the bottom crossbeam 13, and a reinforcing rib 12 is also provided between the curved support beam 11 and the bottom crossbeam 13.

[0019] This achieves the effect of providing sufficient support for the top surface of the tunnel.
