Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a receiving and supporting device. Background Art

[0002] With the continuous progress of society, traffic construction is also getting faster and faster. To meet the development needs of transportation and the social development process, and considering the work efficiency during the bridge construction process, the application of steel girders in bridge construction is becoming more and more extensive. During the installation and erection process of steel girders, many construction site problems such as crossing existing lines and rivers are often encountered. In order to install steel girders safely, conveniently and efficiently, the construction techniques of jacking and towing are usually selected for steel girders in situations such as crossing existing lines and rivers.

[0003] During the construction process of jacking and towing, a receiving seat is arranged on the receiving pier in the conventional construction technique. The receiving seat supports the steel girder, but the receiving seat does not have the function of deviation correction and adjustment. The deviation of the steel girder often occurs during the jacking process, and only temporary deviation correction methods can be adopted, and even the situation of unable to correct the deviation may occur. At the same time, due to the large friction coefficient of the receiving seat during the jacking and towing process, it is often difficult to control the jacking and towing forces.

[0004] Therefore, there is an urgent need for a receiving and supporting device to solve the above problems. Summary of the Utility Model

[0005] In order to solve the technical problems that the existing receiving seat does not have the function of deviation correction and adjustment, and the friction coefficient of the receiving seat is large, resulting in difficult control of the jacking and towing forces, the utility model provides a receiving and supporting device. The function of the sliding plate is to reduce the friction coefficient during the movement of the guide girder, and solve the situation that the friction force is large and difficult to control during the movement of the guide girder; at the same time, deviation correction can be carried out in real time, and the lateral displacement of the guide girder during the jacking and towing process can be corrected and adjusted, so as to realize the precise jacking and towing installation construction of the steel girder.

[0006] The utility model provides a receiving and supporting device, which includes a support cross beam, a moving mechanism and a deviation correction mechanism. The support cross beam is arranged on the transverse and longitudinal beams of the receiving pier. The moving mechanism includes a sliding seat arranged on the support cross beam, and a sliding plate is slidably arranged on the sliding seat. The sliding plate is used to support the guide girder. The deviation correction mechanism includes deviation correction ear seats and hydraulic cylinders. The deviation correction ear seats are oppositely arranged on the support cross beam and are located on both sides of the sliding seat. The tails of the hydraulic cylinders are respectively arranged on the deviation correction ear seats, and the heads of the hydraulic cylinders all face the guide girder and there is a gap between the heads of the hydraulic cylinders and the guide girder.

[0007] Furthermore, the receiving and supporting device further includes an adjusting support. Both ends of the adjusting support are fixedly connected to the support cross beam and the horizontal and vertical beams on the receiving pier respectively. The adjusting support can be used to install the receiving and supporting device on the horizontal and vertical beams at the top of the receiving pier during the jacking and towing installation construction of the steel beam. The adjusting support can adjust the height of the receiving and supporting device to meet the precise requirements of the jacking and towing installation construction of the steel beam.

[0008] Furthermore, one end of the adjusting support is fixedly connected to the support cross beam, and a steel cushion block or unloading block is fixedly connected to the other end of the adjusting support. The steel cushion block or unloading block is fixedly connected to the horizontal and vertical beams on the receiving pier. By adding a steel cushion block or unloading block between the adjusting support and the horizontal and vertical beams on the receiving pier, the overall height of the receiving and supporting device is increased to meet the usage requirements under different working conditions.

[0009] Furthermore, each deviation rectifying ear seat is of a trapezoidal structure. Each deviation rectifying ear seat includes a top plate, a U-shaped side plate, and a bottom plate. The top plate and the bottom plate are respectively fixedly connected to the upper and lower sides of the U-shaped side plate. The bottom plate is fixedly connected to the support cross beam, and the tail of the hydraulic cylinder is fixedly connected to the U-shaped side plate. The tail of the hydraulic cylinder is fixed on the deviation rectifying ear seat, and the deviation rectifying ear seat supports and fixes it.

[0010] Furthermore, a notch is provided on the U-shaped side plate. The cylinder body of the hydraulic cylinder passes through the notch and is locked on the notch of the U-shaped side plate through bolts and nuts.

[0011] Furthermore, a sliding groove is provided on the sliding seat. The sliding plate is embedded in the sliding groove and can slide in the sliding groove. The sliding plate slides in the sliding groove, thereby driving the guiding beam and the main steel beam thereon to move.

[0012] Furthermore, the sliding plate is one of a tetrafluoroethylene sliding plate or an MGE plate.

[0013] Furthermore, tank wheels are provided on the sliding plate. The tank wheels are located in the sliding groove and can slide in the sliding groove.

[0014] Compared with the prior art, the utility model has the following technical effects:

[0015] 1. During the jacking and towing construction process, the guiding beam is placed on the sliding plate. The sliding plate slides on the sliding seat, thereby driving the guiding beam and the main steel beam to move. The function of the sliding plate is to reduce the friction coefficient during the movement of the guiding beam. Since the guiding beam does not directly contact the sliding seat during movement, the guiding beam can move easily under the drive of the sliding plate to meet the installation construction requirements of the jacking and towing of the main steel beam.

[0016] 2. To ensure the axial position of the guide beam during movement and the installation accuracy after the steel beam is moved into place, the lateral displacement of the guide beam during pushing and towing is corrected by adjusting the telescopic amount of the hydraulic cylinders, so as to realize the accurate pushing and towing installation construction of the steel beam. Specifically, two hydraulic cylinders are activated. Generally, the head of the hydraulic cylinder is close to the side of the lower flange of the guide beam and the gap between them is very small, which is convenient for the movement of the guide beam. When the guide beam moves driven by the skateboard, if the guide beam deflects, the heads of the two hydraulic cylinders can correct the position of the guide beam, so that the axis of the guide beam always remains parallel to the axis of the skateboard.

[0030] The present utility model will be further described below in conjunction with the drawings and the detailed description of the embodiments.

[0031] As Figures 1 to 5As shown in the figure, a receiving and supporting device includes a supporting cross beam 2, a moving mechanism and a deviation rectifying mechanism. The supporting cross beam 2 is arranged on the transverse and longitudinal beams 8 of the receiving pier 7, and the bottom of the receiving pier 7 is arranged on the working ground. Refer to Figure 4 , a positional relationship between a guide beam 9 and a main steel beam and a pier on the working ground. The main steel beam is subjected to jacking and dragging installation construction operations to realize the installation with the pier. The moving mechanism includes a sliding seat 3 arranged on the supporting cross beam 2. A sliding plate 4 for reducing the friction coefficient is slidably arranged on the sliding seat 3. The sliding plate 4 is used to support the guide beam 9. Among them, the width of the guide beam 9 is smaller than the width of the sliding plate 4. The middle part of the guide beam 9 is placed on the sliding plate 4. The guide beam 9 is a part of the main steel beam. Usually, the guide beam 9 and the main steel beam are fixedly connected by a locking method; the deviation rectifying mechanism includes deviation rectifying ear seats 5 and hydraulic cylinders 6. The deviation rectifying ear seats 5 are oppositely arranged on the supporting cross beam 2 and are located on both sides of the sliding seat 3. The tails 61 of the hydraulic cylinders 6 are respectively arranged on the deviation rectifying ear seats 5. The heads 62 of the hydraulic cylinders 6 all face the guide beam 9 and there is a gap between the heads 62 of the hydraulic cylinders 6 and the guide beam 9. The guide beam 9 is located in the middle of the heads 62 of the two hydraulic cylinders 6.

[0032] During the jacking and dragging construction process, the guide beam 9 is placed on the sliding plate 4, and the sliding plate 4 slides on the sliding seat 3, thereby driving the guide beam 9 and the main steel beam to move. The guide beam 9 and the main steel beam are relatively heavy, so they will not fall off the sliding plate 4 during movement. The function of the sliding plate 4 is to reduce the friction coefficient during the movement of the guide beam 9. Since the guide beam 9 does not directly contact the sliding seat 3 during movement, the guide beam 9 can move easily under the drive of the sliding plate 4 to meet the installation construction requirements of the jacking and dragging of the main steel beam.

[0033] To ensure the axial position of the guide beam 9 during movement and ensure the accuracy of the installation after the steel beam is moved into place, by adjusting the telescopic amount of the hydraulic cylinder 6, the lateral displacement of the guide beam 9 during the jacking and dragging process is corrected and adjusted, so as to realize the precise jacking and dragging installation construction of the steel beam. Specifically, the two hydraulic cylinders 6 are started, and the heads 62 of the hydraulic cylinders 6 face the guide beam 9 and there is a gap between the heads 62 of the hydraulic cylinders 6 and the guide beam 9. Generally, the heads 62 of the hydraulic cylinders 6 are close to the side of the lower flange of the guide beam 9 and the gap between them is very small. The gap facilitates the movement of the guide beam 9. When the guide beam 9 moves under the drive of the sliding plate 4, if the guide beam 9 deviates, the heads 62 of the two hydraulic cylinders 6 can correct the position of the guide beam 9, so that the axis of the guide beam 9 always remains parallel to the axis of the sliding plate 4.

[0034] For the receiving and supporting device of this embodiment, the function of the sliding plate 4 is to reduce the friction coefficient during the movement of the guide beam 9, solving the problem that it is difficult to control the large friction force during the movement of the guide beam 9; at the same time, deviation rectification can be carried out in real time, and the lateral displacement of the guide beam 9 during the jacking and dragging process is corrected and adjusted, so as to realize the precise jacking and dragging installation construction of the steel beam.

[0035] As an implementable manner, the receiving and supporting device further includes an adjusting support 1. Two ends of the adjusting support 1 are respectively fixedly connected to the supporting cross beam 2 and the horizontal and vertical beam 8 on the receiving pier 7. The adjusting support 1 can be used to install the receiving and supporting device on the horizontal and vertical beam 8 at the top of the receiving pier 7 during the jacking and towing installation construction of the steel beam. The adjusting support 1 can adjust the height of the receiving and supporting device to meet the precise requirements of the jacking and towing installation construction of the steel beam. The adjusting support 1 can be fixedly connected to the supporting cross beam 2 and the horizontal and vertical beam 8 on the receiving pier 7 by welding or locking.

[0036] As an implementable manner, one end of the adjusting support 1 is fixedly connected to the supporting cross beam 2, and a steel cushion block or unloading block is fixedly connected to the other end of the adjusting support 1. The unloading block is of a wedge-shaped structure, and the steel cushion block or unloading block is fixedly connected to the horizontal and vertical beam 8 on the receiving pier 7. By adding a steel cushion block or unloading block between the adjusting support 1 and the horizontal and vertical beam 8 on the receiving pier 7, the overall height of the receiving and supporting device is increased to meet the usage requirements under different working conditions. The steel cushion block or unloading block can be fixedly connected between the adjusting support 1 and the horizontal and vertical beam 8 on the receiving pier 7 by welding or locking.

[0037] Furthermore, the adjusting support 1 includes a first frame body 11 and a supporting grid 12 arranged inside the first frame body 11. The supporting cross beam 2 includes a second frame body 21 and multiple vertical rods 22 uniformly arranged inside the second frame body 21. The adjusting support 1 and the supporting cross beam 2 have high supporting strength and strong rigidity.

[0038] As an implementable manner, each deviation rectifying ear seat 5 is of a trapezoidal structure. Each deviation rectifying ear seat 5 includes a top plate, a U-shaped side plate and a bottom plate. The top plate and the bottom plate are respectively fixedly connected to the upper and lower sides of the U-shaped side plate. The bottom plate is fixedly connected to the supporting cross beam 2, and the tail 61 of the hydraulic cylinder 6 is fixedly connected to the U-shaped side plate by bolts. The tail 61 of the hydraulic cylinder 6 is fixed on the deviation rectifying ear seat 5, and the deviation rectifying ear seat 5 supports and fixes it.

[0039] Furthermore, a notch is provided on the U-shaped side plate, and the cylinder body of the hydraulic cylinder 6 passes through the notch and is locked on the notch of the U-shaped side plate by bolts and nuts. The hydraulic cylinder 6 is arranged on the notch of the U-shaped side plate, making the structure more concise after the hydraulic cylinder 6 and the deviation rectifying ear seat 5 are fixedly connected.

[0040] As an implementable manner, a deviation rectifying block is provided at the head 62 of the hydraulic cylinder 6. Among them, the deviation rectifying block faces the guide beam 9 and there is a gap between the deviation rectifying block and the guide beam 9. Generally, the deviation rectifying block is on the side of the lower flange of the guide beam 9 close to the guide beam 9 and the gap between the two is very small. When the guide beam 9 moves driven by the sliding plate 4, if the guide beam 9 deviates, the two deviation rectifying blocks can correct the position of the guide beam 9, so that the axis of the guide beam 9 always remains parallel to the axis of the sliding plate 4.

[0041] As an implementable mode, a chute is provided on the sliding seat 3, and the sliding plate 4 is embedded in the chute and can slide in the chute. The sliding plate 4 slides in the chute, thereby driving the guide beam 9 and the main steel beam thereon to move.

[0042] As an implementable mode, the sliding plate 4 is one of a polytetrafluoroethylene sliding plate 4 or an MGE plate. When the polytetrafluoroethylene sliding plate 4 or the MGE plate slides in the chute, its own friction coefficient is small, and the frictional force between it and the chute is small. Therefore, the sliding speed of the sliding plate 4 in the chute is increased, which can meet the requirement of accelerating the moving speed of the guide beam 9 and the main steel beam, and reduce the friction coefficient during the movement of the guide beam 9.

[0043] As an implementable mode, a tank wheel or a roller is provided on the sliding plate 4, and the tank wheel or the roller is located in the chute and can slide in the chute. When the tank wheel or the roller slides in the chute, the frictional force between it and the chute is small, which can meet the requirement of accelerating the moving speed of the guide beam 9 and the main steel beam.

For those skilled in the art of this technology, of course, other implementation modes can be easily made by means of replacement or change according to the technical content disclosed in this specification. Therefore, all changes and improvements made in the principles and process conditions of the present invention should be included within the scope of the patent application of the present invention.
