Description

Technical Field

[0001] The invention belongs to the technical field of jacks, in particular to a walking push jack. Background Art

[0002] In the construction of urban overpasses, it is inevitable that the proposed bridge will cross existing highways and railways, and the bridge construction process must not affect the normal operation of highway and railway traffic. When a new urban bridge needs to cross an existing busy highway or rail line, some conventional bridge construction methods cannot complete the new bridge crossing the existing line in a short time. In order to not interrupt the busy traffic line and minimize the impact on the existing traffic line, the jacking method is generally used for construction. That is, the prefabricated beam is guided by steel guide beams and pushed vertically or horizontally by jacks to the designed position to achieve the crossing of the existing line.

[0003] Patent publication number BBB discloses CN110886241B, a bionic steel shoe support system for bridge walking-type jacking construction. The system includes a rubber pad, a pot-type rubber bearing steel box support, and a hydraulic jack, arranged sequentially from top to bottom. A support steel plate is provided above the support end of the hydraulic jack, and a clamping structure is provided around the top of the support end of the hydraulic jack. The top of the clamping structure is connected to the support steel plate, and the upper surface of the support steel plate is detachably connected to the lower surface of the steel box support. The clamping structure includes a first semicircular clamping structure and a second semicircular clamping structure. The side walls of the second semicircular clamping structure are provided with a clamping stiffening plate, and the top of the first semicircular clamping structure is provided with a clamping limit plate. This bionic steel shoe support system for jacking construction can increase the contact area between the jack and the beam to be pushed, reducing damage to the main beam structure during the support process.

[0004] In the current existing technology, the existing walking push jack cannot be adjusted in height by itself when in use. When facing some uneven bottom surfaces of bridges, the different contact forces of the jacks will lead to a reduction in the contact surface of the jacks, thereby increasing the pressure load of a single set of jacks.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] like Figures 1 to 3 and Figure 5As shown, a walking jack push-type jack according to an embodiment of the present invention comprises a conversion frame 1 and a walking jack slide beam 2 arranged in the middle position of the conversion frame 1, a universal hinge assembly 13 arranged on the outer surface of the conversion frame 1, and an intelligent adjustment assembly 14 detachably mounted on the bottom edge position of the conversion frame 1 and the walking jack slide beam 2. A pad beam 9 is provided on the top surface of the conversion frame 1, and a cross beam 12 is movably sleeved on the top surface of the pad beam 9. Support jacks 7 are detachably mounted on the top surface of the conversion frame 1 and on the edge positions on both sides. The intelligent adjustment assembly 14 comprises a vertical height adjustment device 142, and an intelligent adjustment rod 141 is provided on the top surface of the vertical height adjustment device 142. An electric controller 2 143 is provided on the receiving end of the intelligent adjustment rod 141. The outer surface of the electric controller 2 143 is fixedly mounted on the walking jack slide beam 2. The walking jack 3 is fixedly installed on the bottom surface of the plate beam 2 and the top surface of the walking jack skateboard beam 2. The frame adjusting rod 4 is fixedly installed on the top surface of the conversion frame 1 and at the edge positions on both sides. The skateboard beam adjusting rod 5 is provided on the top surface of the walking jack skateboard beam 2 and at the edge positions on all sides. The walking jack lateral limiting device 6 is fixedly installed on the top outer surface of the conversion frame 1. The output end of the walking jack lateral limiting device 6 is set on the top outer surface of the walking jack skateboard beam 2. A plurality of sets of universal hinge devices 8 are fixedly installed on the top inner surface of the conversion frame 1. The bottom surface of the pad beam 9 is fixedly installed on the output end of the support jack 7. A wedge plate 10 is provided on the outer surface of the pad beam 9. A distribution beam plate 11 is fixedly installed on the top surface of the wedge plate 10. The top surface of the distribution beam plate 11 is set on the bottom surface of the cross beam 12.

[0035] Universal hinge devices are provided on the walking jack 3 and the supporting jack 7, and the pad beam 9 can automatically adapt to the changes in the horizontal and vertical slopes of the upper beam 12. Moreover, the universal hinge device automatically adapts to the changes in the horizontal and vertical slopes of the upper beam body, thereby improving the construction efficiency and construction quality, and eliminating the need for manual multiple padding of wedge plates, which can greatly improve the construction efficiency and construction quality. Furthermore, the intelligent adjustment screw with a universal hinge can realize the self-lateral and vertical movement and plane torsion of the frame and the jack. This function is suitable for the jacking of beams with laterally variable width or beams with a relatively small curve radius, which require multiple movements of the jack to adapt to the jacking support point.

[0036] Four intelligent adjustment rods 141 are provided under the frame and the slide beam. The intelligent adjustment rods 141 are mainly used to adjust the overall vertical height of the walking jack 3. When adjusting the longitudinal slope of the main beam or when lowering the beam, the adjustment rods can be used to perform a large range of vertical adjustments without the need for manual installation and removal of pads. The adjustment rods are provided with an electric controller 143, which can automatically adjust the height of the electric controller 143 through the control system without manual operation, achieving a high degree of automation.

[0037] The intelligent adjustment rod is mainly used for adjusting the overall vertical height of the walking jack. During the jacking process, the longitudinal slope of the main beam is adjusted or the beam is dropped. Especially for the jacking construction of the variable cross-section height beam, the adjustment rod can be used for large-scale vertical adjustment without the need for manual installation and removal of pads multiple times.

[0038] like Figure 1-Figure 2 and Figures 6 to 9 As shown, four sets of auxiliary hydraulic rods a3 are fixedly installed on the outer surface of the four sides of the distribution beam plate 11, and a cavity a1 is opened on the inner wall surface of the distribution beam plate 11. The output end of the auxiliary hydraulic rod a3 extends to the inner wall surface of the cavity a1, and the output end of the auxiliary hydraulic rod a3 is fixedly connected to the arc-shaped pushing block a4. The top surface of the distribution beam plate 11 and the edge positions of the four sides are provided with a limited docking groove a2. The interior of the cavity a1 is movably sleeved with a pad lifting plate a5, and the bottom surface of the pad lifting plate a5 is provided with a There is an arc-shaped lifting groove a6, and limited docking columns a7 are fixedly installed on the four edges of the raised lifting plate a5. The outer surface of the limited docking column a7 is movably sleeved on the inner wall of the limited docking groove a2. A non-slip and wear-resistant pad a8 is provided on the top surface of the raised lifting plate a5, and the surface of the non-slip and wear-resistant pad a8 is movably fitted on the bottom surface of the beam 12. A raised plate a9 is fixedly connected to the inner wall surface of the bottom of the cavity a1, and the top surface of the raised plate a9 is movably fitted on the bottom surface of the raised lifting plate a5.

[0039] When the distribution beams 11 on the top of the walking jacks 3 and the supporting jacks 7 are fitted on the bottom surface of the beam 12, when a group of distribution beams 11 is not completely fitted on the bottom surface of the beam 12, the walking jacks 3 and the supporting jacks 7 stop moving upward, and cooperate with the auxiliary hydraulic rod a3 to push the arc-shaped pushing block a4, and use the arc-shaped pushing block a4 to lift the bottom surface of the padding and lifting plate a5, so that the padding and lifting plate a5 is raised, and the top surface of the padding and lifting plate a5 is fitted on the bottom surface of the beam 12. The rising of the padding and lifting plate a5 fills and closes the gap between the walking jacks 3 and the supporting jacks 7 and the beam 12, so that the force on the bridge is uniform, making the pushing process more stable.

[0040] When the auxiliary hydraulic rod a3 pushes the arc-shaped pushing block a4, the arc degree on the outer surface of the arc-shaped pushing block a4 is used to fit the arc-shaped lifting groove a6 on the outer surface of the bottom of the pad lifting plate a5, and the pad lifting plate a5 is fit and squeezed onto the bottom surface of the beam 12. After one group of the walking jacks 3 and the supporting jacks 7 are fitted, the beam 12 begins to be lifted. The overweight beam 12 will press down the pad lifting plate a5. At this time, the four groups of arc-shaped pushing blocks a4 are used to disperse the weight of the downward pressure of the pad lifting plate a5, so as to avoid the pad lifting plate a5 being subjected to excessive pressure load and causing the auxiliary hydraulic rod a3 to generate excessive pressure.

[0041] When the pad raising and lifting plate a5 is raised, if the gap between the pad raising and lifting plate a5 and the crossbeam 12 is too large, as the arc-shaped pushing block a4 continues to go deeper, the arc-shaped pushing block a4 will overlap the bottom surface of the pad raising and lifting plate a5, such as Figure 6 As shown, the planar support on the top surface of the arc-shaped push block a4 is overlapped on the bottom surface of the elevated lifting plate a5, so that the downward pressure of the crossbeam 12 on the elevated lifting plate a5 can be directly transmitted to the top surface of the walking jack 3 or the support jack 7 through the arc-shaped push block a4;

[0042] If the gap between the padding and lifting plate a5 and the crossbeam 12 is too small, the bottom edges of the padding and lifting plate a5 will overlap the top middle position of the arc-shaped pushing block a4. By utilizing the surface slope and gradual height of the arc-shaped pushing block a4, the padding and lifting plate a5 can be effectively overlapped at any position on the surface of the arc-shaped pushing block a4 according to different gaps, such as Figure 7 As shown, 15 provides support points and support strength, and the downward pushing force of 15 on the arc-shaped pushing block a4 can be dispersed to the surface of the four groups of auxiliary hydraulic rods a3, avoiding the effect that excessive downward pressure of the lifting plate a5 will cause excessive load on the single group of auxiliary hydraulic rods a3 and damage the single group of auxiliary hydraulic rods a3.

[0043] like Figures 1 to 2 and Figure 4 As shown, the universal hinge assembly 13 includes multiple groups of limit frames 134, and the outer surfaces of the two groups of limit frames 134 are fixedly mounted on the outer surfaces of the conversion frame 1 and the walking jack skateboard beam 2 respectively. A universal hinge group head 131 is movably sleeved on one end of one group of limit frames 134, and a jack 135 is provided on one end of the other group of limit frames 134. An adjusting screw rod 132 is provided on the outer surface of the universal hinge group head 131, and an electric controller 133 is provided on the outer surface of the adjusting screw rod 132.

[0044] Six groups of walking jacks 3 are set between the frame and the skateboard beam. The device is mainly composed of a jack 135, an adjusting screw rod 132, an electric controller 133 and a universal hinge head 131. It can automatically adjust the length and angle. Multiple adjustment devices are uniformly controlled by a hydraulic electronic control system and can be adjusted to different lengths and angles synchronously or asynchronously to meet the working process and rotation process of the pushing system, the frame beam and the whole. No manual operation is required, and the degree of automation is high.

[0045] Working principle: a universal hinge device is provided on the walking jack 3 and the supporting jack 7, and the pad beam 9 can automatically adapt to the changes in the horizontal and vertical slopes of the upper cross beam 12. In addition, the universal hinge device is provided to automatically adapt to the changes in the horizontal and vertical slopes of the upper beam body, thereby improving construction efficiency and construction quality, and eliminating the need for manual multiple insertion of wedge plates, which can greatly improve construction efficiency and construction quality; four intelligent adjustment rods 141 are provided under the frame and the skateboard beam. The intelligent adjustment rods 141 are mainly used for adjusting the overall vertical height of the walking jack 3. When adjusting the longitudinal slope of the main beam or when lowering the beam, the adjustment rods can be used to perform a large range of vertical adjustments without the need for manual multiple installation and removal of pads; the adjustment rods are provided with an electric controller 143, and the height of the electric controller 143 can be automatically adjusted through the control system without manual operation, achieving a high degree of automation.

[0046] Six sets of walking jacks 3 are set between the frame and the skateboard beam. The device mainly consists of a jack 135, an adjusting screw 132, an electric controller 133 and a universal hinge group head 131. The length and angle can be automatically adjusted. Multiple adjustment devices are uniformly controlled by a hydraulic electric control system. Different lengths and angles can be adjusted synchronously or asynchronously to meet the working and rotation processes of the pushing system, the frame beam and the whole. No manual operation is required, and the degree of automation is high.

[0047] When the distribution beams 11 on the top of the walking jacks 3 and the supporting jacks 7 are fitted on the bottom surface of the beam 12, when a group of distribution beams 11 is not completely fitted on the bottom surface of the beam 12, the walking jacks 3 and the supporting jacks 7 stop moving upward, and cooperate with the auxiliary hydraulic rod a3 to push the arc-shaped pushing block a4, and use the arc-shaped pushing block a4 to lift the bottom surface of the padding and lifting plate a5, so that the padding and lifting plate a5 is raised, and the top surface of the padding and lifting plate a5 is fitted on the bottom surface of the beam 12. The rising of the padding and lifting plate a5 fills and closes the gap between the walking jacks 3 and the supporting jacks 7 and the beam 12, so that the force on the bridge is uniform, making the pushing process more stable.

[0048] When the auxiliary hydraulic rod a3 pushes the arc-shaped pushing block a4, the arc degree on the outer surface of the arc-shaped pushing block a4 is used to fit the arc-shaped lifting groove a6 on the outer surface of the bottom of the pad lifting plate a5, and the pad lifting plate a5 is fit and squeezed onto the bottom surface of the beam 12. After one group of the walking jacks 3 and the supporting jacks 7 are fitted, the beam 12 begins to be lifted. The overweight beam 12 will press down the pad lifting plate a5. At this time, the four groups of arc-shaped pushing blocks a4 are used to disperse the weight of the downward pressure of the pad lifting plate a5, so as to avoid the pad lifting plate a5 being subjected to excessive pressure load and causing the auxiliary hydraulic rod a3 to generate excessive pressure.

[0049] When the pad raising and lifting plate a5 is raised, if the gap between the pad raising and lifting plate a5 and the crossbeam 12 is too large, as the arc-shaped pushing block a4 continues to go deeper, the arc-shaped pushing block a4 will overlap the bottom surface of the pad raising and lifting plate a5, such as Figure 6 As shown, the planar support on the top surface of the arc-shaped push block a4 is overlapped on the bottom surface of the elevated lifting plate a5, so that the downward pressure of the crossbeam 12 on the elevated lifting plate a5 can be directly transmitted to the top surface of the walking jack 3 or the support jack 7 through the arc-shaped push block a4;

[0050] If the gap between the padding and lifting plate a5 and the crossbeam 12 is too small, the bottom edges of the padding and lifting plate a5 will overlap the top middle position of the arc-shaped pushing block a4. By utilizing the surface slope and gradual height of the arc-shaped pushing block a4, the padding and lifting plate a5 can be effectively overlapped at any position on the surface of the arc-shaped pushing block a4 according to different gaps, such as Figure 7 As shown, 15 provides support points and support strength, and the downward pushing force of 15 on the arc-shaped pushing block a4 can be dispersed to the surface of the four groups of auxiliary hydraulic rods a3, avoiding the effect that excessive downward pressure of the lifting plate a5 will cause excessive load on the single group of auxiliary hydraulic rods a3 and damage the single group of auxiliary hydraulic rods a3.
