Abstract
The utility model relates to an unloading support seat, which comprises a seat body, and is characterized in that: a sliding groove is arranged on the seat body; a sliding block structure is arranged on the sliding groove, and comprises a lower sliding block embedded in the sliding groove and an upper sliding block embedded with the top surface of the lower sliding block; a sliding surface is arranged between the upper sliding block and the lower sliding block; the sliding surface and the horizontal plane form an acute angle; the upper sliding block and the lower sliding block slide along the sliding surface; the seat body is provided with a horizontally arranged screw rod; one end of the screw rod is connected with the lower sliding block to drive the lower sliding block to move back and forth along the sliding groove; and the other end of the screw rod penetrates through a side wall of the seat body, and is fixed on the side wall. The unloading support seat has the advantages of adopting a simple structure, being easy to operate, needing low cost, being suitable for unloading a component bearing a large tonnage, being capable of unloading automatically without needing a hydraulic jack, shifting the weight of the component onto a permanent support seat, and being capable of ensuring the component to keep the originally adjusted state during the shifting process.
Description
Technical field
The utility model belongs to the constructional engineering machinery field, and particularly a kind of unloading bearing is applicable to unloading carrying large-tonnage member.
Background technology
In building engineering construction, for the high accuracy of guaranteeing rail beam (or other similar components) is installed, at first use the three-dimensional adjusting device of hydraulic jack, the 3 d pose of rail beam is adjusted to the right place, replace three-dimensional adjusting device with the unloading bearing again, and keep member attitude and the precision adjust, the secondary that special concrete or mortar are carried out in permanent rest base gap waters and smashes then, after the concrete (or mortar) for the treatment of bearing support reaches design and allows unloading intensity, can utilize this unloading bearing directly to unload, to permanent bearing, the member attitude can remain unchanged with the member Load Transfer.But at present, there is baroque problem in existing unloading bearing, and bearing do not have the function of off-load, needs the hydraulic jack off-load, and program is loaded down with trivial details.In view of the foregoing, demand developing a kind of unloading bearing of novel structure urgently, to satisfy the demand that people improve constantly.
Summary of the invention
The purpose of this utility model has provided a kind of unloading bearing, has solved the deficiencies in the prior art.
The purpose of this utility model is achieved in that a kind of unloading bearing, comprise: pedestal, it is characterized in that: a chute is arranged on the described pedestal, chute is provided with slide block structure, this slide block structure include in the chute that is embedded on the pedestal sliding block with the sliding block end face top shoe of embedding mutually, form a slide plane up and down between the slide block, and slide plane is horizontal by acute angle, on, sliding block slides along this slide plane, the screw rod that one horizontal positioned is arranged, an end of screw rod links to each other with sliding block, can drive sliding block and move around along chute, the other end passes the sidewall of pedestal, is fixed on the sidewall.
Locating hole is arranged on top shoe, and the sidewall that a bolt passes pedestal is inserted in this locating hole, fixedly top shoe.
On the bolt between sidewall and the top shoe, be with sleeve pipe.
The utility model has the advantages that: simple in structure, easy operating, with low cost, be applicable to unloading carrying large-tonnage member, do not need hydraulic jack just can unload voluntarily, the weight of member is transformed on the permanent bearing, and can guarantees that member keeps original attitude of adjusting in transfer process.
Description of drawings
Accompanying drawing 1 is a topology view of the present utility model.
Below in conjunction with drawings and Examples the utility model is elaborated.
The specific embodiment
Among the figure, a kind of unloading bearing, comprise: pedestal 1, it is characterized in that: on the described pedestal 1 chute is arranged, chute is provided with slide block structure 2, this slide block structure include in the chute that is embedded on the pedestal sliding block 21 with the sliding block 21 end faces top shoe 22 of embedding mutually, slide block 21 up and down, form a slide plane between 22, and slide plane is horizontal by acute angle, on, sliding block slides along this slide plane, and the screw rod 3 of a horizontal positioned is arranged, one end of screw rod 3 links to each other with sliding block 21, can drive sliding block 21 and move around along chute, the other end passes the sidewall 5 of pedestal 1, is fixed on the sidewall 5.
On top shoe 22 locating hole is arranged, the sidewall that a bolt 6 passes pedestal is inserted in this locating hole, and fixedly top shoe 22.
On the bolt 6 between sidewall 5 and the top shoe 22, be with sleeve pipe 4, heighten the rigidity of sidewall.
In building engineering construction, for the high accuracy of guaranteeing rail beam (or other similar components) is installed, at first use the three-dimensional adjusting device of hydraulic jack, the 3 d pose of rail beam is adjusted to the right place, replace three-dimensional adjusting device with the unloading bearing again, at this moment, the staff can withstand rail beam with the unloading bearing, bear its load, and keep member attitude and the precision adjust, the secondary that special concrete or mortar are carried out in permanent rest base gap waters and smashes then, after the concrete (or mortar) for the treatment of bearing support reaches design and allows unloading intensity, can utilize this unloading bearing directly to unload.
During the unloading of unloading bearing, remove the bolt that is used to locate of top shoe, only need to use the spanner rotary screw then, screw rod drives sliding block and moves along chute, then the relative sliding block of top shoe can slowly reduce the height of unloading bearing to lower slider, reaches the purpose of off-load, to permanent bearing, the member attitude can remain unchanged with the member Load Transfer.The angle of slide plane and horizontal plane is determined according to the friction factor between two slide blocks when design.
Below only expressed embodiment of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
The utility model advantage is: simple in structure, and easy operating, with low cost, be applicable to unloading carrying large-tonnage member, do not need hydraulic jack just can unload voluntarily, the weight of member is transformed on the permanent bearing, and can guarantees that member keeps original attitude of adjusting in transfer process.
