Abstract
The utility model discloses an automatic spacing card for a hydraulic bracket testing stand, which is configured in a way mainly consisting of the steps of connecting one end of a double-side tooth rack connecting rod (7) with the piston rod of a jack (8), connecting the other end of the connecting rod with a right semicircular ring (4) through a pin shaft (2), meshing the other end with two gears (6), connecting two single-side tooth rack connecting rods (3) with a left semicircular ring (1) through the pin shaft (2) respectively, and meshing the two single-side tooth rack connecting rods (3) with the two gears (6) respectively. As the piston rod of the jack (8) expands and contracts, the double-side tooth rack connecting rod (7) is led to conduct reciprocating motion, driving the left and the right semicircular rings to move in the opposite directions through the two gears (6) in the middle, a catch wheel (5) and the two single-side tooth rack connecting rods (3), thereby realizing clamping and releasing. The utility model solves the problems of the bracket testing stand spacing card, including large weight, high position, reliance on manual job mounting the card, and inconvenience in adjustment, and has the advantages of high efficiency and safety, simple structure, and convenient operation.
Description
Affiliated technical field
The utility model relates to a kind of hydraulic bracket test-bed automatic spacing card.
Background technology
Hydraulic bracket test-bed, be the equipment that the coal mine fully-mechanized mining hydraulic support is carried out performance test.It mainly is made up of four root posts and upper and lower base, whole formation one rectangular frame.For satisfying the requirement of seriation hydraulic support performance test, testing table carries out structural design by the size of maximum support height (6.5 meters).Its principle of work is that hydraulic support is exerted pressure, and checks every performance index such as each parts stressing conditions, structural stability, failure mode and hydraulic system sealing with this understanding.Its method is that hydraulic support is put into testing table, according to being used spacing card at experiment table column differing heights place by the frame type of test hydraulic support, height, spacing to set cap, when the hydraulic support back timber is raised to herein, can not move upward, import highly pressurised liquid to required pressure to the hydraulic support support cylinder this moment, and time pressurize in accordance with regulations, thus the various performance of operating condition of check hydraulic support under test pressure.
At present, its supporting construction height of the hydraulic support that uses under the coal mine is from 0.7 meter to 6.5 meters, maximum rated working resistance is from 2500KN to 15000KN, single frame weight is between 4 tons to 60 tons, thereby will be when the hydraulic support of unit-frame type and structure make a service test, spacing card on the testing table needs to adjust at the enterprising luggage card of column, to adapt to the needs of differing heights stented test.Because the testing table whole height surpasses 10 meters, test pressure is very big, and for guaranteeing safety and satisfy testing requirements, the position-limit card junction structure is bigger, and weight surpasses 200 kilograms, and its fixed form is by bolt locking.Spacing calorie requirement adjustment when the hydraulic support of differing heights frame type is tested, at present this being installed adjusted the full manually-operated of leaning on, and be very inconvenient, time-consuming, and poor stability.
Summary of the invention
For solving hydraulic bracket test-bed spacing card position height, Heavy Weight, by inconvenient, the unsafe problem of manually being installed, the utility model provides a kind of hydraulic bracket test-bed automatic spacing card of new structure, drive a two-sided tooth bar connecting link, two gears and two single-side rack connecting rods with a hydraulic jack, and then make identical left and right two the semicircle spacing rings of diameter can realize opening automatically with closed, solved the spacing inconvenient problem of card that clamps of testing table.
The technical scheme in the invention for solving the technical problem is: with identical left and right two semicircular rings of diameter, design has two boss and tooling pin axis hole on left semicircle shape ring diameter direction, place, right semicircular ring centre position design one boss and tooling pin axis hole.One end of two-sided tooth bar connecting rod links to each other with the piston rod of lifting jack, the other end links to each other with the right semi-circle ring by bearing pin, be meshed with two gears simultaneously, left semicircle shape ring links to each other with two single-side rack connecting rods respectively by bearing pin, and two single-side rack connecting rods are meshed with two gears respectively.The left and right motion of the two-sided tooth bar connecting rod of drive of stretching, contract by the hydraulic jack piston rod, effect by two gears and two single-side rack connecting rods, make left semicircle shape ring and right semicircular ring make move toward one another, thereby realize that left and right two semicircular rings clamp and unclamp on testing table column relevant position, reach convenient, fast, carry out the automatic adjustment of the spacing card of testing table safely.
The beneficial effects of the utility model are: solved hydraulic bracket test-bed spacing card owing to Heavy Weight, position height, adjust the difficult problem of inconvenience, improved work efficiency and security by manually being installed, and simple in structure, easy to operate.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the section of structure of the hydraulic bracket test-bed automatic spacing card of the utility model.
Fig. 2 is a left semicircle shape ring part drawing.
Fig. 3 is a right semicircular ring part drawing.
Embodiment
As shown in Figure 1 to Figure 3, the utility model comprises identical left and right two semicircular rings of diameter, design has two boss and is processed with pin shaft hole on left semicircle shape ring (1) diametric(al), by bearing pin (2) left semicircle shape ring (1) is linked to each other respectively with two single-side rack connecting rods (3), one boss is arranged and be processed with pin shaft hole in the design of place, right semicircular ring (4) centre position, by bearing pin (2) the right semicircular ring is linked to each other with an end of two-sided tooth bar connecting rod (7), the other end of two-sided tooth bar connecting rod links to each other with the piston rod of lifting jack.Its principle of work is:
Behind the logical liquid of lifting jack (8), drive two-sided tooth bar connecting rod (7) and right semicircular ring (4) to left movement by the piston rod of lifting jack (8); Simultaneously, by two-sided tooth bar connecting rod (7), single-side rack connecting rod (3) and middle two gears (6) and gear wheel (5), driving left semicircle shape ring (1) moves right, thereby left and right two semicircular rings are stuck in the testing table column respective annular groove, realization is spacing to the hydraulic support back timber, just can carry out the pressure test of support.
After off-test, the contraction of the piston rod of lifting jack (8) drives two-sided tooth bar connecting rod (7) and right semicircular ring (4) moves right; Simultaneously, by two-sided tooth bar connecting rod (7), single-side rack connecting rod (3) and middle two gears (6) and gear wheel (5), drive left semicircle shape ring (1) to left movement, two semicircular rings withdraw from from testing table column ring groove about making, and finish a complete working cycle.
Claims (1)
1. hydraulic bracket test-bed automatic spacing card, comprise left semicircle shape ring (1) and right semicircular ring (4) that diameter is identical, bearing pin (2), single-side rack connecting rod (3), two-sided tooth bar connecting rod (7), gear wheel (5), gear (6), lifting jack parts such as (8), it is characterized in that: two-sided tooth bar connecting rod (7) one ends link to each other with the piston rod of lifting jack (8), the other end links to each other with right semi-circle ring (4) by bearing pin (2), be meshed with two gears (6) simultaneously, left semicircle shape ring (1) links to each other with two single-side rack connecting rods (3) respectively by bearing pin (2), and two single-side rack connecting rods (3) are meshed with two gears (6) respectively.
