Description

height-adjustable stand

technical field

The invention relates to a support seat used for adjusting the line shape and height of a structure during building construction, in particular to a height-adjustable support seat.

Background technique

In the process of building construction, the control of the alignment of the structure is extremely critical. In order to ensure the alignment and height of the structure construction, it is necessary to copy pads during the construction process. The common method of copying pads is to copy the pads on the load at the bottom of the load according to the actual required pad height. The amount of pads used is large and the reuse rate is low. At the same time, under the action of a large-tonnage load, if the height of the copying pad needs to be adjusted accurately, a large-tonnage jack matching the load-bearing tonnage needs to be configured, which is not conducive to saving costs.

Contents of the invention

The technical problem to be solved by the present invention is to solve the problems of inconvenient and high cost in the precise adjustment of the alignment of structures during the building construction process.

In order to solve the above technical problems, the technical solution adopted by the present invention is to provide a height-adjustable support base, including left and right middle sliders, lower sliders, upper sliders and two sets of adjustment devices, the left and right The shape and size of the middle sliders are the same, the longitudinal sections are respectively trapezoidal, and the tips are opposite; On the lower slider; the lower surface of the upper slider is adapted to the upper surface of the left and right middle sliders respectively, and the upper slider is placed on the left and right middle sliders; the two sets of adjustment devices are symmetrical Set on the front and back of the left and right middle sliders, each set of lead screw adjustment devices includes a threaded sleeve and left and right lead screws screwed on both ends of the threaded sleeve respectively. The thread turns in opposite directions and the outer ends are respectively fixed to the front and rear surfaces of the left and right middle sliders. When the threaded sleeve is rotated, the left and right screw respectively drive the left and right middle sliders to move horizontally to adjust the large tonnage support. Seat lift.

As an improvement of the present invention, the left and right end surfaces of the left and right middle sliders are respectively provided with lubricating oil passages leading to the contact surfaces of the upper and lower sliders and the left and right middle sliders, and the entrances of the lubricating oil passages With grease fitting.

It also includes a slide plate on which the lower slider is placed.

In the present invention, the height adjustment of the large-tonnage support seat is realized by applying a relatively small force to the sleeve, and by manually screwing the sleeve, the left and right middle sliders are horizontally displaced inwards or outwards. Increase or decrease the overall height of the support base, so that the elevation of the bottom surface of the load is raised or lowered to meet the expected height of the load. Due to the use of the sleeve screw drive mechanism, it can carry large tonnage loads and adjust them accurately.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings.

As shown in Fig. 1 and Fig. 2, the present invention includes a slide plate 10 and a support seat placed on the slide plate 10. The slide plate 10 is made of polymer material MGB with a lower friction coefficient and a higher bearing capacity, and the support seat can pass through The slide plate 10 is conveniently slid into the bottom gap of the load to support the load.

Described support base comprises left and right middle slide block 24,29, lower slide block 30, upper slide block 26 and two sets of adjusting devices, left and right middle slide block 24,29 have the same shape and size, and their longitudinal sections are respectively trapezoidal , and the tips are opposite; the upper surface of the lower slider 30 is adapted to the lower surfaces of the left and right middle sliders 24, 29 respectively, and the left and right middle sliders 24, 29 are respectively placed on the lower slider 30; The lower surface of the slide block 26 is adapted to the upper surfaces of the left and right middle slide blocks 24,29 respectively, and the upper slide block 26 is placed on the left and right middle slide blocks 24,29; 1. On the front and back of the right middle slide block 24,29, each set of adjustment device includes a threaded sleeve 27 and left and right lead screws 25,28 screwed on respectively at the two ends of the threaded sleeve, left and right lead screws 25 , 28 are screwed in the opposite direction and the outer ends are respectively fixed by the front and rear surfaces of the hinge seat 21 and the left and right middle slide blocks 24 and 29, and the threaded sleeve 27 is rotated, and the left and right lead screws 25 and 28 respectively affect the left and right sides. The right middle slide block 24,29 moves along the horizontal direction so as to adjust the lifting of this large tonnage support seat.

The left and right end faces of the left and right middle sliders 24,29 are respectively provided with lubricating oil passages 23 leading to the contact surfaces of the upper and lower sliders 26,30 and the left and right middle sliders 24,29, and the lubricating oil passages 23 Grease fittings 22 are respectively provided at the entrances. Lubricating grease is filled between the contact surfaces of the sliders through the grease nipple 22 to reduce the coefficient of static friction between the sliders, so that the lifting operation of the support seat is more labor-saving and its service life is improved.

The inclination angles of the left and right middle sliders 24, 29 of the present invention are jointly determined according to the maximum height difference that needs to be adjusted actually, the coefficient of friction between the sliders and the maximum internal force that the screw mandrel can bear.

The present invention is not limited to the above-mentioned best implementation mode, and anyone should know that any structural changes made under the inspiration of the present invention, and any technical solutions that are identical or similar to the present invention, all fall within the protection scope of the present invention.
