Description

Technical Field

[0001] This utility model belongs to the field of marine petroleum technology, and in particular relates to a device for moving a pier on flat ground. Background Technology

[0002] Offshore oil platforms are constructed by assembling many precast panels. Before construction, precast panels need to be placed on shims in a workshop or on a concrete floor as needed. These shims are used to fix the precast panels to the ground. Traditionally, forklifts or cranes are used to place and move these shims.

[0003] Using forklifts or cranes to move the platform greatly increases the platform construction cost. Sometimes, when the crane or forklift schedule is tight, it often causes work delays. It also increases the need for vehicle coordination. Forklifts and cranes require qualified special personnel to operate, which places high demands on the personnel.

[0004] Therefore, there is an urgent need to design a ground-level moving device for the piers to solve the aforementioned problem of pier movement. Utility Model Content

[0005] To address the technical problems mentioned in the background art, such as high construction costs, limited usage time of forklifts or cranes, and limited operators when moving piers using forklifts or cranes, a device for moving piers on flat ground is provided to solve the problem of moving piers on flat ground.

[0006] To achieve the above objectives, the specific technical solution of the ground-moving device for the pier of this utility model is as follows:

[0007] A device for moving a pier on flat ground comprises a first crossbeam, a second crossbeam, and a third crossbeam. The first, second, and third crossbeams are located on the same horizontal plane. The second crossbeam is vertically connected to one end of the first crossbeam. The third crossbeam is slidably mounted on the end of the first crossbeam away from the second crossbeam. Scissor jacks are mounted on both the second and third crossbeams. The scissor jacks are adjusted to contact the lower surface of the upper flange plate of the pier. Each scissor jack has a support rod that engages with a limiting groove in the second and third crossbeams to support it. The scissor jacks lift the pier so that its lower flange plate abuts against the limiting grooves of the second and third crossbeams to fix the pier. Both the second and third crossbeams are equipped with pulley assemblies. By pulling a traction rod connected to the first crossbeam, the pier can be moved on flat ground.

[0008] Furthermore, a square steel bar is connected to the end of the third crossbeam, and the square steel bar is fitted onto the first crossbeam so that the third crossbeam can slide along the length of the first crossbeam.

[0009] Furthermore, trapezoidal beams are provided on both the second and third crossbeams, and scissor jacks are installed on the trapezoidal beams.

[0010] Furthermore, the pulley assembly includes directional wheels and omnidirectional wheels. Omnidirectional wheels are provided at the ends of the second and third crossbeams near the first crossbeam, and directional wheels are provided at the ends of the second and third crossbeams away from the first crossbeam.

[0011] Furthermore, the second and third crossbeams are both equipped with limiting steel on the side away from the trapezoidal beam, and the limiting steel is located between the swivel wheel and the directional wheel.

[0012] Furthermore, positioning bolts are screwed onto the square steel. Adjusting the positioning bolts adjusts the distance between the second and third crossbeams.

[0013] Furthermore, each of the two scissor jacks has a support rod hinged to its side, and the end of the support rod away from the scissor jack is engaged in a limiting groove.

[0014] Furthermore, multiple limiting grooves are provided along the upper surfaces of the second and third crossbeams so that after the scissor jack lifts the pad, the end of the support rod away from the scissor jack is engaged in the corresponding limiting groove.

[0015] Furthermore, multiple limiting grooves are provided on both sides of the trapezoidal beam.

[0016] Furthermore, a traction rod is hinged to the first crossbeam, which is used to move the pad to the placement position.

[0017] The ground-moving device for the pier of this utility model has the following advantages:

[0018] The first, second, and third crossbeams form an integral structure. The second and third crossbeams are placed between the upper and lower flange plates of the pier. Adjusting the scissor jacks to engage with the lower surface of the upper flange plate raises the pier off the ground, and engaging the upper surface of the lower flange plate with the limiting steel to secure the pier. Then, by pulling the traction rod, the pier can be moved on the ground. This application ensures the stability and safety of the pier during transportation, is lightweight and flexible, and eliminates or reduces reliance on cranes or forklifts when moving the pier. It also eliminates the need for drivers and specialized personnel such as crane operators, thus reducing construction costs. Attached Figure Description

For example, in the claims, any of the claimed embodiments can be used in any combination.

[0025] The following is a reference to the appendix. Figure 1 To be continued Figure 2 This invention describes a device for moving a platform on flat ground.

[0026] like Figure 1 As shown, the ground-level moving device for the pier in this utility model consists of a first crossbeam 1, a second crossbeam 2, and a third crossbeam 3. The first crossbeam 1, the second crossbeam 2, and the third crossbeam 3 are located on the same horizontal plane. The second crossbeam 2 is vertically connected to one end of the first crossbeam 1. The third crossbeam 3 is slidably mounted on the end of the first crossbeam 1 away from the second crossbeam 2. Both the second crossbeam 2 and the third crossbeam 3 are equipped with scissor jacks 4. The scissor jacks 4 are adjusted so that they contact the lower surface of the upper flange plate of the pier. The scissor jacks 4 are equipped with support rods 5, which are engaged in the limiting grooves 6 of the second crossbeam 2 and the third crossbeam 3 to support the scissor jacks 4.

[0027] The scissor jack 4 lifts the pad so that the lower flange of the pad abuts against the limiting steel 7 of the second crossbeam 2 and the third crossbeam 3 to fix the pad; both the second crossbeam 2 and the third crossbeam 3 are equipped with pulley assemblies, and the pad can be moved on the flat ground by pulling the traction rod 8 connected to the first crossbeam 1.

[0028] The first crossbeam 1, the second crossbeam 2, and the third crossbeam 3 form an integral structure. The second crossbeam 2 and the third crossbeam 3 are placed between the upper and lower flange plates of the pier. The scissor jack 4 is adjusted to abut against the lower surface of the upper flange plate, lifting the pier off the ground. The upper surface of the lower flange plate of the pier abuts against the limiting steel 7, thus fixing the pier. Then, by pulling the traction rod 8, the pier can be moved on the ground. This application ensures the stability and safety of the pier during transportation, is lightweight and flexible, and can eliminate or reduce the reliance on cranes or forklifts when moving the pier. It also eliminates the need for drivers and special personnel such as crane operators, thus reducing construction costs.

[0029] Furthermore, such as Figure 1 As shown, a square steel 9 is connected to the end of the third crossbeam 3, and the square steel 9 is sleeved on the first crossbeam 1 so that the third crossbeam 3 can slide along the length direction of the first crossbeam 1; both the second crossbeam 2 and the third crossbeam 3 are provided with trapezoidal beams 10, and scissor jacks 4 are provided on the trapezoidal beams 10; the pulley assembly includes a directional wheel 11 and a universal wheel 12, and both the second crossbeam 2 and the third crossbeam 3 are provided with universal wheels 12 at the end near the first crossbeam 1, and both the second crossbeam 2 and the third crossbeam 3 are provided with directional wheels 11 at the end away from the first crossbeam 1.

[0030] In this embodiment, a second crossbeam 2 is vertically welded to one end of the first crossbeam 1, and a third crossbeam 3 is fitted onto the end of the first crossbeam 1 away from the second crossbeam 2 via a square steel 9, so that the third crossbeam 3 can slide along the length direction of the first crossbeam 1. Preferably, the third crossbeam 3 is always kept on the same horizontal plane as the second crossbeam 2, and one end of the third crossbeam 3 is welded to the square steel 9, thereby forming an opening at the end of the second crossbeam 2 and the third crossbeam 3 away from the first crossbeam 1, so that the second crossbeam 2 and the third crossbeam 3 can be placed on both sides of the pier.

[0031] Preferably, the support pier is a support structure formed by welding steel plates vertically to the middle I-beam and the upper and lower ends. Through the opening between the second crossbeam 2 and the third crossbeam 3, the second crossbeam 2 and the third crossbeam 3 can be inserted into the support pier without passing through the middle I-beam.

[0032] Trapezoidal beams 10 are fixedly installed on the upper surfaces of the middle part of the second crossbeam 2 and the third crossbeam 3, and scissor jacks 4 are installed on the trapezoidal beams 10 respectively. The trapezoidal beams 10 can increase the initial height of the scissor jacks 4 so that the scissor jacks 4 can lift piers of various heights.

[0033] Preferably, the second crossbeam 2 and the third crossbeam 3 are each provided with a universal wheel 12 at the end near the first crossbeam 1, and a directional wheel 11 is provided at the end of the second crossbeam 2 and the third crossbeam 3 away from the first crossbeam 1, so that the pad can move on the ground in a specified direction.

[0034] Furthermore, such as Figure 1and Figure 2 As shown, the second crossbeam 2 and the third crossbeam 3 are both provided with limiting steel 7 on the side away from the trapezoidal beam 10. The limiting steel 7 is located between the universal wheel 12 and the directional wheel 11. The square steel 9 is screwed with positioning bolts 13. The positioning bolts 13 are adjusted to adjust the distance between the second crossbeam 2 and the third crossbeam 3. The two scissor jacks 4 are respectively hinged to support rods 5 on both sides. The end of the support rod 5 away from the scissor jack 4 is locked in the limiting groove 6.

[0035] In this embodiment, limiting steel 7 is fixedly provided on the side of the second crossbeam 2 and the third crossbeam 3 away from the trapezoidal beam 10. Preferably, two limiting steel 7 are provided at intervals on the lower surface of the second crossbeam 2 and the third crossbeam 3. The two limiting steel 7 are fixedly provided between the universal wheel 12 and the directional wheel 11. When the scissor jack 4 lifts the pad, the upper surface of the lower flange plate of the pad abuts against the limiting steel 7, so that the pad is lifted off the ground and fixed, thereby realizing the movement of the pad.

[0036] Preferably, a positioning bolt 13 is screwed onto the square steel 9. Loosening the positioning bolt 13 allows the third crossbeam 3 to move along the length direction of the first crossbeam 1, thereby changing the distance between the second crossbeam 2 and the third crossbeam 3. Tightening the positioning bolt 13 fixes the position of the third crossbeam 3.

[0037] Both sides of the scissor jack 4 are hinged with support rods 5. The free end of the support rod 5 is inserted into the limiting groove 6 when the scissor jack 4 abuts against the upper flange plate of the support block, so as to increase the stability and safety of the scissor jack 4 under force. When the scissor jack 4 does not lift the support block, the support rod 5 is retracted.

[0038] Furthermore, such as Figure 1 As shown, multiple limiting grooves 6 are provided on the upper surfaces of the second crossbeam 2 and the third crossbeam 3, so that after the scissor jack 4 lifts the pad, the end of the support rod 5 away from the scissor jack 4 is engaged in the corresponding limiting groove 6; multiple limiting grooves 6 are provided on both sides of the trapezoidal beam 10; a traction rod 8 is hinged on the first crossbeam 1, and the pad is moved to the placement position by the traction rod 8.

[0039] In this embodiment, preferably, multiple limiting strips are provided on the second crossbeam 2 and the third crossbeam 3, and limiting grooves 6 are formed between adjacent limiting strips. Furthermore, multiple limiting grooves 6 are provided on both sides of the trapezoidal beam 10 to ensure that when the scissor jack 1 lifts the pads at different heights, the free end of the support rod 5 can be engaged in the limiting groove 6 to ensure the stability of the scissor jack 4.

[0040] After the pier is fixed, the construction workers can move the pier on the ground in the specified direction by pulling the traction rod 8.

[0041] The working principle of the ground-moving device for the platform in this utility model is as follows:

[0042] First, slide the square steel 9 to change the distance between the second crossbeam 2 and the third crossbeam 3, so that the distance between the second crossbeam 2 and the third crossbeam 3 is consistent with the width of the I-beam in the middle of the pier to be moved, and then tighten the positioning bolt 13.

[0043] Then, push the second crossbeam 2 and the third crossbeam 3 to be placed on both sides of the middle I-beam, and position the scissor jack 4 between the upper flange plate and the lower flange plate of the pier.

[0044] Then, adjust the scissor jack 4 so that it contacts the lower surface of the upper flange plate of the pad block and lifts the pad block so that the lower flange plate of the pad block is off the ground and abuts against the limiting steel 7.

[0045] Then, the free ends of the support rods 5 hinged to both sides of the scissor jack 4 are engaged in the corresponding limiting grooves 6;

[0046] Then, pull the traction rod 8 to move the pad to the designated position;

[0047] Finally, disengage the free end of the support rod 5 from the limiting groove 6, and adjust the scissor jack 4 to lower the pad to the designated location.

[0048] Based on the ground-level moving device for the pier, this utility model forms an integral structure with a first crossbeam 1, a second crossbeam 2, and a third crossbeam 3. The second crossbeam 2 and the third crossbeam 3 are placed between the upper and lower flange plates of the pier. The scissor jack 4 is adjusted to abut against the lower surface of the upper flange plate, causing the pier placed on the ground to be lifted off the ground. The upper surface of the lower flange plate of the pier abuts against the limiting steel 7, thus fixing the pier. Then, by pulling the traction rod 8, the pier can be moved on the ground. This application ensures the stability and safety of the pier during transportation, is lightweight and flexible, and can eliminate or reduce the reliance on cranes or forklifts when moving the pier. It also eliminates the need for drivers and special personnel such as crane operators, thus reducing construction costs.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
