Embodiment 2

[0047] A kind of excavation work face temporary support equipment, its structure is as shown in embodiment 1, the difference is, as shown in Figure 5, the quantity of lifting platform 7 is 6, and lifting platform 7 comprises two lifting hydraulic cylinders 71 and The lifting top plate 72 located on the upper part of the two lifting hydraulic cylinders 71 and the lifting hydraulic cylinder 71 of the lifting platform can keep synchronous elongation, and the elongation can also be adjusted according to the complex situation of the roadway. The bottom of the lifting hydraulic cylinder 71 is fixed on the connecting rod 12 , the top of the extension rod of the lifting hydraulic cylinder 71 is connected with the lifting roof 72 through a multi-degree-of-freedom connector 73 to ensure that the lifting roof 72 is self-adjusting to adapt to the complex shape of the roadway top. The multi-degree-of-freedom connector 73 here is a connector composed of a pair of ordinary hinges with a relat...

Embodiment 3

[0051] A kind of temporary support equipment for excavation work, its structure is as shown in embodiment 2, the difference is, as figure 1 , 2 As shown, the bottoms of the three square steel pipes without connecting rods are fixedly provided with an inverted U-shaped guide rail 2, as the walking track of the guide mechanism 4 and the drive mechanism 5, and a pin rail 3 is fixedly installed above the square steel pipe in the middle position. Used to cooperate with the drive gear 52 inside the drive mechanism;

[0052] Such as figure 2 As shown, the drive mechanism 5 includes a drive box body 51, a drive gear 52 cooperating with the pin track 3 is installed on the top of the drive box body 51, a motor 53 is arranged on the outside of the drive box body 51, and the output shaft of the motor 53 is connected to the drive gear 52. connected to drive the drive gear 52 to rotate, thereby realizing the relative movement between the pin rail 3 and the drive gear 52;

Abstract

The invention discloses driving face temporary support equipment and a working method thereof, and belongs to the field of roadway support. The equipment comprises a front beam frame; the front beam frame comprises three square steel pipes, and connecting rods for connecting the three square steel pipes; at least four sets of connecting rods are arranged at the front end of the front beam frame, and a set of connecting rods is arranged at the back end; a driving mechanism is arranged on the square steel pipe in middle; guide mechanisms are arranged on the square steel pipes on two sides; a clamping device is fixedly arranged at the upper part of the driving mechanism; clamping mechanisms are mounted at the upper parts of the guide mechanisms through undercarriages; multiple sets of liftingplatforms are uniformly arranged on the four sets of connecting rods at the front end of the front beam frame; projection brackets are arranged at the front ends of the square steel pipes on two sides; and a tail leveling device is arranged at the back end of the front beam frame. The anchor net and steel strip pavement and the temporary support work are once realized to effectively prevent the operation of workers under empty tops; and the autonomous movement of the temporary support equipment is realized to achieve important significance on improvement of the support efficiency and reduction of the manpower and the labor intensity.

Description

technical field [0001] The invention relates to a temporary support device for a tunneling working face and a working method thereof, belonging to the technical field of roadway support. Background technique [0002] During the roadway excavation process, the supporting work of the underground roadway is the top priority for safe production. Temporary support refers to the support erected to prevent the roof from falling before the permanent support is erected, and its purpose is to protect the safety of construction personnel. At present, the temporary support of coal mines is mostly supported by the front beam support. The roadheader cuts and exits. The construction personnel carry the anchor net and steel belt, and lift them to the top of the roadway, and then the front beam moves forward to support the anchor net and steel belt. , and then use solid wood to reinforce, and then carry out the operation of bolting, and finally the front beam is moved back, and the roadhead...
