TECHNICAL FIELD
[0001] The utility model belongs to the technical field of pot support, especially relates to a height adjustment big angle pot support. BACKGROUND
[0002] Bridge support is the important structural component of connecting bridge superstructure and substructure. Bridge support can reliably transmit the counterforce and deformation of superstructure to the substructure of bridge. Under the action of load, temperature, concrete shrinkage and creep, the support can adapt to the rotation angle and displacement of superstructure, so that the superstructure can freely deform without additional additional internal force.
[0003] For cable-stayed bridge, cable bridge and bridge with large span, the required rotation angle is often large. When the bridge adopts large rotation angle, ball-type support is generally used instead, but the damping effect of ball-type support is not as good as that of pot-type rubber support. Bridges with high damping effect requirements generally use pot-type rubber support, and the currently used pot-type rubber support includes upper seat plate, middle seat plate and lower seat plate, and has a pot cavity on the lower seat plate. The middle seat plate is located in the pot cavity, and a pressure bearing pad is arranged in the pot cavity below the middle seat plate. The pot-type rubber support has the following defects: first, the rotation angle of the pot-type rubber support is realized by the pressure bearing pad in the pot, and because the compression performance of the pressure bearing pad is limited, the rotation angle design of the ordinary pot-type rubber support is limited to the compression performance of the pressure bearing pad, and it is difficult to design a larger rotation angle; second, in the long-term use of the bridge, the piers often have different degrees of settlement. When the bridge settles, the support and the beam body are out of engagement. At this time, the support does not bear the force of the upper structure load, and the counterforce and deformation of the upper structure cannot be reliably transmitted to the substructure of the bridge. In this case, the bridge has safety hazards. At this time, the height of the support needs to be adjusted. The height of the support is generally adjusted by two methods: the first is to replace the support with a height matching the support, and the second is to adjust the height of the support itself. Obviously, the first scheme has a high cost. The height adjustment of the general support is 20-30mm. When the height adjustment is too large, the filling medium is easy to overflow. UTILITY MODEL CONTENTS
[0004] The technical problem to be solved by the utility model is to provide a height adjustment big angle pot-type rubber support with good damping effect, large support rotation angle, convenient height adjustment, high adjustment height, non-overflowing filling medium, non-out-of-engagement, high safety factor.
[0005] In order to solve the above problems, the technical solution adopted by the utility model of a height-adjustable large-angle basin-type support is as follows: it includes an upper seat plate, a middle seat plate and a lower seat plate, the middle seat plate includes a middle seat core plate located in the middle and a basin sleeve located around the middle seat core plate, and an upper basin cavity and a lower basin cavity are formed above and below the middle seat core plate respectively; the lower seat plate includes a lower seat base plate and a lower center plate located in the middle of the lower seat base plate; an upper pressure pad is provided at the bottom of the upper basin cavity, an upper lining plate is provided above the upper pressure pad, and the upper seat plate is located at the Above the upper lining plate, the upper surface of the upper lining plate is higher than the upper surface of the basin sleeve, and the lower surface of the upper lining plate is located in the upper basin cavity; a lower pressure pad is provided on the top of the lower basin cavity, and the lower center plate is located below the lower pressure plate, and the upper surface of the lower center plate is inserted into the lower basin cavity; a height adjustment channel opening on the outside of the basin sleeve is provided in the middle seat core plate and the basin sleeve, and an upper height adjustment port and a lower height adjustment port are respectively provided at the bottom of the upper basin cavity and the top of the lower basin cavity, and the upper height adjustment port and the lower height adjustment port are connected to the height adjustment channel.
[0006] Its additional technical features are:
[0007] A friction pair is provided between the upper seat plate and the upper lining plate;
[0008] The upper lining plate is fixedly connected to the upper seat plate.
[0009] The utility model provides a height-adjustable large-angle basin-type support, which has the following advantages compared with the prior art: First, since the height-adjustable large-angle basin-type support includes an upper seat plate, a middle seat plate and a lower seat plate, the middle seat plate includes a middle seat core plate located in the middle and a basin sleeve located around the middle seat core plate, and an upper basin cavity and a lower basin cavity are formed above and below the middle seat core plate respectively; the lower seat plate includes a lower seat base plate and a lower center plate located in the middle of the lower seat base plate; an upper pressure pad is provided at the bottom of the upper basin cavity , an upper lining plate is provided above the upper pressure pad, the upper seat plate is located above the upper lining plate, the upper surface of the upper lining plate is higher than the upper surface of the basin sleeve, and the lower surface of the upper lining plate is located in the upper basin cavity; a lower pressure pad is provided on the top of the lower basin cavity, the lower center plate is located below the lower pressure plate, and the upper surface of the lower center plate is inserted into the lower basin cavity; a height adjustment channel opening on the outside of the basin sleeve is provided in the middle seat core plate and the basin sleeve, and a plurality of channels are provided at the bottom of the upper basin cavity and the top of the lower basin cavity respectively. The upper height adjustment port and the lower height adjustment port are connected to the height adjustment channel. The basin-type support includes two pelvic cavities, an upper pelvic cavity and a lower pelvic cavity. A pressure pad is provided in each pelvic cavity, which has a better shock absorption effect and greatly increases the rotation angle of the support. When the height of the support needs to be adjusted, a height adjustment medium is injected into the upper pelvic cavity and the lower pelvic cavity at the same time. The medium is spread flat on the bottom of the upper pelvic cavity and the top of the lower pelvic cavity. When adjusting the same height, the overflow of the medium can be effectively avoided, and the adjustment height is further increased; Secondly, since a friction pair is provided between the upper seat plate and the upper lining plate, for a support with a bidirectional sliding or unidirectional sliding function, by providing a friction pair between the upper seat plate and the upper lining plate, the friction force between the upper seat plate and the upper lining plate is reduced, and the sliding function is better realized; thirdly, since the upper lining plate is fixedly connected to the upper seat plate, for a fixed support, the upper lining plate is fixedly connected to the upper seat plate, the shock absorption and isolation effect is better, and horizontal movement between the upper seat plate and the lower seat plate is avoided.
