Problems solved by technology

[0003] The current composite beams mainly rely on manpower for construction, which leads to several problems in the construction of composite beams: 1. There is no mechanized supporting equipment and there are potential safety hazards; 2. The anchor cable drilled and the anchor cable opened on the beam The holes do not match and the position is deviated; 3. The installation of the anchor cable is time-consuming and labor-intensive, the construction efficiency is low and the installation is difficult; 4. After the anchor cable is installed, manual tensioning is required
Difficult to meet the efficiency and safety requirements of the existing roadway for composite beam support construction

Embodiment 1

[0030] In a typical embodiment of the present disclosure, such as Figure 1-Figure 2 As shown, a construction device for the roadway composite beam support system is given.

[0031] Aiming at the problems of low efficiency and poor safety in roadway composite beam support at present, the composite beam is installed through the construction device of the roadway composite beam support system, and the composite beam is supported by the first bracket located in front, and the conveying mechanism 9 Establish the connection relationship between the high position of the composite beam and the low position of the second support at the rear, use the drilling rig 3 and the tensioner 17 to complete the drilling and anchor cable tensioning work, reduce the installation difficulty of the composite beam, and improve the construction of the composite beam in the roadway efficiency and safety.

[0032] The construction device of the roadway composite beam support system mainly includes the ...

Embodiment 2

[0065] In another embodiment of the present disclosure, as Figure 1-Figure 2 As shown, a construction method of roadway composite beam support system is given.

[0066] Utilize the roadway composite beam support system construction device in embodiment 1, comprise the following steps:

[0067] Place the combined beam on the top surface of the supporting plate 11, the lifting frame 14 lifts the supporting plate 11 and the combined beam to the support position, and simultaneously drives one end of the conveying mechanism 9 to rise, and the second support 5 moves with the other end of the conveying mechanism 9;

[0068] The drilling rig 3 passes through the support plate 11 to drill holes in the composite beam and the surrounding rock, and the anchor cable clamp 10 carries the anchor cable and transports it to the anchor cable tensioner 17;

[0069] During the drilling process, the position of the drilling rig 3 is adjusted to drill holes in multiple set positions of the compos...

Abstract

The invention provides a roadway composite beam supporting system construction device and method, and relates to the technical field of composite beam construction. The problems of lower efficiency and poorer safety during roadway composite beam supporting at present are solved. A first support located in front supports and lifts a composite beam, a conveying mechanism establishes the connection relation between the high position where the composite beam is located and the low position of a second support located behind, drilling and anchor cable tensioning work is completed through a drilling machine and a tensioning device, the installation difficulty of the composite beam is reduced, and the construction efficiency and safety of the composite beam in a roadway are improved. The roadway composite beam supporting system construction device comprises a first support, a conveying mechanism and a second support, the first support comprises a bearing plate and a lifting machine frame which are connected, one end of the conveying mechanism is hinged to the lower part of the bearing plate, the other end of the conveying mechanism is hinged to the second support, a plurality of sets of anchor cable clamps are arranged on the conveying mechanism at intervals, the lower part of the bearing plate is connected with an anchor cable tensioning device through a position adjusting mechanism, and a drilling machine with the working end facing the bearing plate is connected to the part, below the bearing plate, of the lifting machine frame.

Description

technical field [0001] The disclosure relates to the technical field of composite beam construction, in particular to a construction device and method for a roadway composite beam support system. Background technique [0002] With the development of coal mining to the deep underground, the geological conditions are gradually deteriorating, and the roadway stability control plays a very important role in the safe mining of coal mines. At present, in the coal roadway support technology, the composite beam support technology is an effective deep roadway Compared with simple bolt and cable support, the support method can better maintain the stability of the roadway roof. [0003] The current composite beams mainly rely on manpower for construction, which leads to several problems in the construction of composite beams: 1. There is no mechanized supporting equipment and there are potential safety hazards; 2. The anchor cable drilled and the anchor cable opened on the beam The ho...
