Problems solved by technology

In the actual working conditions, the roadway is not flat head-on. Because the roadheader has not fully excavated, there is a certain slope at the end of the roadway, and the coal mine ground in the roadway is complicated. Comprehensive support, and the installation is too time-consuming and laborious

Embodiment 1

[0041] Such as Figure 1 to Figure 6 As shown, the present invention provides a purely mechanical semi-automatic mobile roadway temporary support device, comprising a support top plate 2, a cross support 26, a front beam 5, a front beam track wheel 4, a migration steel rope 25, a steel belt 1 and Anchor rod 3, wherein the upper end of the cross support 26 is hinged under the supporting roof 2, and the steel belt 1 is temporarily laid on the front probe beam, and is arranged in the middle of the two supporting roofs 2. The steel belt 1 adopts a W-shaped steel belt, and the specification of the steel belt is The length and width are determined by the width of the roadway, and the steel belt is arranged with 5 eyelets. The front beam 5 passes through the front beam track wheel 4, and the front beam 5 passes through the lower end of the cross support 26 at the same time, and the upper end of the front beam track wheel 4 is fixedly connected with the anchor rod 3, and the anchor ro...

Embodiment 2

[0043]A purely mechanical semi-automatic mobile roadway temporary support device, the structure is as described in Embodiment 1, the difference is that: the front beam track wheel 4 includes the upper half of the buckle 7, the lower half of the bracket 8, the latch 6 and the roller 9. The upper half of the gusset 7 is connected with the lower half of the bracket 8 through a bolt, and the roller 9 is installed at the lower end of the lower half of the bracket 8. The upper half of the gusset 7 is provided with a threaded hole, and is fixedly connected with the anchor rod 3 through threads.

Embodiment 3

[0045] A purely mechanical semi-automatic mobile roadway temporary support device, the structure is as described in Embodiment 1, the difference is that: the cross support 26 includes a frame 11, and the frame 11 is provided with track wheels 10, winch sets and hoists, and the track The wheel 10 is in rolling contact with the front probe beam 5, and the winch group includes connecting rods that are hinged to each other. The connecting rod at the top is hinged with the support top plate 2, and the connecting rod at the bottom is provided with hoist wires, which link to each other with the hoist.

Abstract

The invention relates to a purely-mechanical semi-automatic mobile roadway temporary supporting device and a working method, and belongs to the technical field of coal mine supporting equipment. The purely-mechanical semi-automatic mobile roadway temporary supporting device comprises two supporting frame top plates, a crossed support, a forepoling beam, a forepoling beam rail wheel, a migrating steel rope, a steel belt, an anchor rod and a reinforcing mesh, wherein the upper end of the crossed support is hinged with the part below the supporting frame top plates; the steel belt is temporarilypaved on the forepoling beam; the steel belt is arranged in the middle of the two supporting frame top plates; one end of the forepoling beam continuously passes through the forepoling beam rail wheeland the other end of the forepoling beam continuously passes through the lower end of the crossed support; the upper end of the forepoling beam rail wheel is fixedly connected with the anchor rod; the migrating steel rope passes through the forepoling beam rail wheel and is hung and mounted at the ring position of the forepoling beam; and forward movement of the forepoling beam is realized by pulling the steel rope. Supporting and movement of the device are realized by mechanical structures; and the purely-mechanical semi-automatic mobile roadway temporary supporting device is simple in structure, solid and durable and guarantees the work safety while improving the labor efficiency.

Description

technical field [0001] The invention relates to a purely mechanical semi-automatic mobile roadway temporary support device and a working method, belonging to the technical field of coal mine support equipment. Background technique [0002] Temporary support refers to the support erected to prevent the roof from falling before the permanent support is erected. The temporary support mainly plays a role in protecting the safety of construction personnel. Any operation carried out without temporary support is called open-top operation, which is a serious violation of regulations and is absolutely prohibited. [0003] Although there is already an integrated tunnel boring machine, but it still needs a long way to go before it is fully popularized. Considering the cost and cost performance of upgrading the roadheader, many coal mines have not adopted it. At present, most of the exposed surfaces of tunnels in coal mines are temporarily supported by manual support or by installing t...
