Abstract
The utility model relates to scraper blade conveyer telescopic tails for a coal mine workers to mine the working face, in particular to asymmetrically-arranged telescopic tails of an oil cylinder. The asymmetrically-arranged telescopic tails of the oil cylinder comprise a driving part, a tail support (1) and a fixing support (2) arranged at the lower end of the tail support (1). The asymmetrically-arranged telescopic tails of the oil cylinder are characterized in that one side of a baffle on the tail support (1) and one side of a baffle on the fixing support (2) of the asymmetrically-arranged telescopic tails are respectively and fixedly provided with an oil cylinder linkage base (3), and a hydraulic oil cylinder (4) is installed on the two oil cylinder linkage bases (3). One side of a shovel plate on the tail support (1) and one side of a shovel plate on the fixing support (2) of the telescopic tails are also respectively and fixedly provided with an oil cylinder linkage base (3), and a hydraulic oil cylinder (4) is also installed on the two oil cylinder linkage bases (3). The asymmetric-arrangement telescopic tails of the oil cylinder ensures the coal cutting effect of a coal cutter on the tails portions of the telescopic tails.
Description
Technical field
The utility model relates to a kind of drag conveyor telescopic machine tail, especially telescopic machine tail of oil cylinder asymmetric arrangement of using for colliery pit mining work plane.
Background technology
At present, colliery pit mining Scraper Conveyor in Mining Face scraper chain is crossed pine can cause jumping chain accident, and tension can increase the wearing and tearing of conveyer, reduces the application life of drag conveyor, so the general hydraulically extensible tail that adopts is regulated in the tensioning of scraper chain.Traditional telescopic machine tail hydraulic jack is arranged symmetrically in the both sides of drive end unit, the connection ear of fixed hydraulic oil cylinder is welded on respectively on aircraft tail shelf and the fixed mount, in order to reduce the tail height, to satisfy the requirement of coal mine worker working face mining, the hydraulic jack of drive end unit both sides is arranged in telescopic machine tail drive division gusset piece front.When reality is used, because the shovel board side cylinder is arranged forward (near the telescopic machine tail small end), it is limited that coal-winning machine drives to the position of telescopic machine tail afterbody, affect coal-winning machine in the coal cutting effect of telescopic machine tail afterbody, in the well worker work plane of Part load, exist the tail Triangle Coal to cut the situation of not saturating or cut branch frame back timber.
The utility model content
The purpose of this utility model provides a kind of telescopic machine tail of oil cylinder asymmetric arrangement, can make the coal mining function drive to as far as possible the afterbody of telescopic machine tail when reducing the tail height, guarantees that coal-winning machine is in the afterbody coal cutting effect of telescopic machine tail.
A kind of telescopic machine tail of oil cylinder asymmetric arrangement, comprise drive division, the fixed mount of aircraft tail shelf and aircraft tail shelf lower end, its special feature is: aircraft tail shelf and fixed mount overhead gage one side at telescopic machine tail are fixed with an oil cylinder connection seat separately, and at these two oil cylinder connection seats hydraulic jack are installed; Shovel board one side also is fixed with an oil cylinder connection seat separately on the aircraft tail shelf of telescopic machine tail and fixed mount, and on these two oil cylinder connection seats hydraulic jack is installed also; Wherein the oil cylinder connection seat of aircraft tail shelf overhead gage one side of telescopic machine tail is arranged in the close little end position of telescopic machine tail of front end of telescopic machine tail drive division gusset piece, and the oil cylinder connection seat of shovel board one side is arranged in the large end position of tail on the aircraft tail shelf of telescopic machine tail.
Wherein the oil cylinder connection seat is installed on the bolt block on aircraft tail shelf and the fixed mount by alignment pin.
Wherein the bolt block position on aircraft tail shelf and the fixed mount adopts bilateral symmetry to arrange.
The utility model provides a kind of telescopic machine tail of oil cylinder asymmetric arrangement, by telescopic machine tail baffle plate side cylinder connection seat is arranged in telescopic machine tail drive division gusset piece front, it is high to have reduced tail axle group switching centre, and telescopic machine tail shovel board side cylinder connection seat is arranged near the large end position of tail, make the coal mining function drive to smoothly the afterbody of telescopic machine tail, guaranteed the coal cutting effect of coal-winning machine at the telescopic machine tail afterbody.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is a kind of telescopic machine tail of oil cylinder asymmetric arrangement, comprise drive division, the fixed mount 2 of aircraft tail shelf 1 and aircraft tail shelf 1 lower end, on the aircraft tail shelf 1 of telescopic machine tail and baffle plate one side (the power part side namely is installed) on the fixed mount 2 be fixed with separately an oil cylinder connection seat 3, and at these two oil cylinder connection seats 3 hydraulic jack 4 is installed; On the aircraft tail shelf 1 of telescopic machine tail and shovel board one side (the power part side namely is not installed) on the fixed mount 2 also be fixed with separately an oil cylinder connection seat 3, and on these two oil cylinder connection seats 3, a hydraulic jack 4 is installed also; Wherein the oil cylinder connection seat 3 of the aircraft tail shelf 1 baffle plate side of telescopic machine tail is arranged in the front end of telescopic machine tail drive division gusset piece 5 near the little end position of telescopic machine tail of the little end position of telescopic machine tail or front end, and the oil cylinder connection seat 3 of the aircraft tail shelf 1 shovel board side of telescopic machine tail then is arranged in the large end position of tail.
Wherein oil cylinder connection seat 3 is installed on the bolt block on aircraft tail shelf 1 and the fixed mount 2 by alignment pin, easy to connect, and the bolt block position bilateral symmetry on the aircraft tail shelf 1, fixed mount 2 is arranged (each side is equipped with the bolt block position near large end with near two positions of small end), can satisfy left and right work plane installation requirement.
Claims (3)
1. the telescopic machine tail of an oil cylinder asymmetric arrangement, comprise drive division, the fixed mount (2) of aircraft tail shelf (1) and aircraft tail shelf (1) lower end, it is characterized in that: aircraft tail shelf (1) and fixed mount (2) overhead gage one side at telescopic machine tail are fixed with an oil cylinder connection seat (3) separately, and at these two oil cylinder connection seats (3) hydraulic jack (4) are installed; Aircraft tail shelf (1) and upper shovel board one side of fixed mount (2) at telescopic machine tail also are fixed with an oil cylinder connection seat (3) separately, and on these two oil cylinder connection seats (3) hydraulic jack (4) are installed also; Wherein the oil cylinder connection seat (3) of the aircraft tail shelf of telescopic machine tail (1) overhead gage one side is arranged in the close little end position of telescopic machine tail of front end of telescopic machine tail drive division gusset piece (5), and the oil cylinder connection seat (3) of upper shovel board one side of the aircraft tail shelf of telescopic machine tail (1) is arranged in the large end position of tail.
