Abstract

The utility model discloses a light end bracket which comprises a front top beam, a rear top beam, a front base, a middle base, a rear base, three upright posts and a rear upright post; the upright post at the front end is connected with the front end of the front top beam and the front end of the front base; the upright post in the middle is connected with the rear end of the front top beam and the front end of the middle base; the upright post at the rear end is connected with the front end of the rear top beam and the rear end of the middle base; the rear end of the rear top beam is connected with the rear end of a shield beam; the front end of the shield beam is connected with a refuse baffle; the rear upright post is respectively connected with the front end of the rear base and the middle rear end of the shield beam; and the middle front end of the shield beam is respectively connected with a front connecting rod and a rear connecting rod connected with the rear end of the rear base. The light end bracket has the characteristics of high supporting efficiency and light weight, and is convenient to move.

Description

Light-duty face end support

Technical field

The utility model relates to a kind of coal excavation apparatus, specifically is the light-duty face end support that a kind of fully mechanized coal face uses.

Background technology

The fully-mechanized mining working faces end head supporting is to perplex, influence one of outstanding difficult problem of fully mechanized coal face supporting safety, coal mining efficient and mining costs for a long time always.The layout general layout of existing equipment adopts timber plate girder and monomer column support pattern under the situation that does not have the termination frame, have following defective: (1) labor strength is big, and timber plate girder and monomer column all need manually transport, install and prop drawing; (2) support cost height, part material can not be realized recycling, no matter adopt face termination condition quality, the timber plate girder of input is once and drops into, can not be multiplexing; (3) prop drawing difficulty, potential safety hazard is big, and when pressure was big, post pierced base plate easily, is not easy prop drawing; (4) supporting efficient is low, and the monomer column supporting intensity is low, and the damage amount is bigger; (5) the end support time long, each end support time needs 30 minutes at least.

Summary of the invention

Technical problem to be solved in the utility model is the light-duty face end support that a kind of supporting efficient height, in light weight, conveniently moving will be provided.

Address the above problem, a kind of light-duty face end support described in the utility model, comprise preceding back timber, back back timber, preceding base, middle base, rear base and three root posts and a rear column, back timber front end and preceding base front end before the column of front end connects, top beam rear end and middle base front end before middle column connects, the column of rear end connects back back timber front end and middle end Cuo rear end, back top beam rear end is connected with the caving shield rear end, the caving shield front end connects waste rock board, rear column is connected with the middle rear end of caving shield with the front end of rear base respectively, and the middle front end of caving shield connects front rod and the back link that is connected with the rear base rear end respectively.

Face end support described in the utility model is simple in structure, and is in light weight, by pass oil cylinder with elevating conveyor and face end support each other fulcrum move forward, conveniently moving, supporting efficient height can solve the end support problem.

Compared with prior art, the utlity model has following characteristics: it is convenient that (1) moves frame, shortened the end support time, and each termination frame-shift time only needs 10 minutes.Not during the use side head bracket, with monomer column and log hut combined supporting mode, shut down and do support work approximately half an hour, equipment operation rate is low, the per unit area yield raising is restricted, the support material consumption is big, need shut down about 10 minutes to the termination behind the use side head bracket at every turn, cut 3 cutter coals by per tour, every day, three classes of production cut the calculating of 9 cutter coals altogether, compared with prior art, can reduce about 2 hours of downtime every day, created advantage for the further raising of adopting the face per unit area yield, alleviated labor strength, only need operate the valve group and just can finish the frame work that moves; (2) labor strength obviously alleviates, and support capacity significantly strengthens, and safety factor is improved; (3) support cost is low, and plate-girder, monomer column consumption obviously reduce, and under the good situation of termination condition, does not need to drop into timber plate girder; When inclement condition, just on top board, overlap plate-girder, the timber plate girder consumption obviously reduces; (4) supporting intensity height, potential safety hazard is little, and working resistance reaches 11582KN; Have a good application prospect.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done and to be specified.

A kind of light-duty face end support described in the utility model, as shown in Figure 1, back timber 1 before comprising, back back timber 2, preceding base 3, middle base 4, rear base 5 and three root posts and a rear column 7, back timber 1 front end and preceding base 3 front ends before the column 61 of front end connects, back timber 1 rear end and middle base 4 front ends before middle column 62 connects, the column 63 of rear end connects back back timber 2 front ends and middle end Cuo 4 rear ends, back back timber 2 rear ends are connected with caving shield 8 rear ends, caving shield 8 front ends connect waste rock board 9, rear column 7 is connected with the middle rear end of caving shield 8 with the front end of rear base 5 respectively, and the middle front end of caving shield 8 connects front rod 10 and the back link 11 that is connected with rear base 5 rear ends respectively.Preceding back timber 1 front end connects face guard 12, and face guard 12 middle parts are connected by one two power bar 13 with preceding base 3 front ends.The both sides of preceding back timber 1 are respectively equipped with anti-coal plate 14.In Coal Production, need the light-duty face end support of two covers to be installed in the both sides in tunnel respectively, middlely connect with hydraulic cylinder 18, the light-duty face end support of two covers is to slip 17 supporting uses (shown in Fig. 2,3) with elevating conveyor 15 and preceding slide 16, back.
