[0032] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0033] As Figure 1 , Figure 4 shown, a specific embodiment of the walking jacking and sliding equipment provided by this embodiment includes: a sliding base 1, a sliding box body 2, a first driving member 4, and a second driving member 5. The sliding box body 2 is installed in the sliding base 1. The bottom of the sliding box body 2 is provided with rollers 3, and the rolling ends of the rollers 3 are connected to the inner bottom wall of the sliding base 1. The driving end of the first driving member 4 is connected to the sliding box body 2. The first driving member 4 is used to drive the sliding box body 2 to move horizontally in the sliding base 1. The second driving member 5 is installed on the sliding box body 2, and the driving end of the second driving member 5 is adapted to support on the bottom of the beam body 6. The second driving member 5 is used to drive the beam body 6 to move up and down. Multiple sliding bases 1 can be provided at the bottom of each beam body 6, or one sliding base 1 can be provided. The sliding base 1 is installed on the precast yard. In this embodiment, the number of sliding bases 1 is two, which are respectively located at both ends of the beam body 6. The first driving member 4 and the second driving member 5 are both oil cylinders. The first driving member 4 is horizontally arranged, and the second driving member 5 is vertically arranged. In addition, as an alternative embodiment, the first driving member 4 and the second driving member 5 can also be electric push rods, motors, etc.
[0034] The walking jacking and sliding equipment provided in this embodiment has a sliding box body 2 installed in a sliding base 1 through rollers 3. When the sliding box body 2 moves horizontally driven by a first driving member 4, the friction between the rollers 3 and the sliding box body 2 is small, which not only reduces energy consumption but also does not cause wear to the sliding box body 2 and the sliding base 1, ensuring a long service life and good use effect.
[0035] As Figure 2 , Figure 3 shown, in the walking jacking and sliding equipment provided in this embodiment, a partition 7 is provided on the side wall of the sliding base 1. The partition 7 has a guiding groove 8 for passing through the sliding box body 2. The guiding groove 8 of the partition 7 plays a role in restricting the sliding box body 2, enabling the sliding box body 2 to move along a fixed path and being more stable during the movement. Additionally, as an alternative implementation, rollers 3 can also be respectively provided on both side surfaces of the sliding box body 2, and the rolling ends of the rollers 3 on both side surfaces are respectively connected to the two side walls of the sliding base 1.
[0036] As Figure 4 shown, in the walking jacking and sliding equipment provided in this embodiment, the sliding box body 2 includes a mounting box 9 and a support block 10 connected to the middle position at the bottom of the mounting box 9. The support block 10 is a long strip. The second driving member 5 is located inside the mounting box 9. The support block 10 and the guiding groove 8 cooperate with each other to realize the restriction of the mounting box 9. The mounting box 9 has a larger width and a larger accommodation space.
[0037] As Figure 4 shown, in the walking jacking and sliding equipment provided in this embodiment, there are multiple sliding box bodies 2 arranged at intervals. Adjacent two sliding box bodies 2 are connected by a connecting rod 11. Each sliding box body 2 is installed with a second driving member 5. Multiple sliding box bodies 2 can install more second driving members 5, which is more convenient for supporting the beam body 6. Additionally, as an alternative implementation, multiple second driving members 5 can also be installed in a single sliding box body 2.
[0038] As Figure 4 shown, in the walking jacking and sliding equipment provided in this embodiment, the connecting rod 11 is a round rod and has at least two arranged at intervals in the height direction. The two round rods can firmly connect adjacent sliding box bodies 2. Additionally, as an alternative implementation, the connecting rod 11 can also be a rectangular rod with a larger height, and then only one connecting rod 11 is needed to connect adjacent two sliding box bodies 2.
[0039] As Figure 4As shown in the figure, in the walking jacking and sliding equipment provided in this embodiment, it further includes: a photoelectric sensor 12, which is installed at the end of the sliding base 1. The photoelectric sensor 12 is electrically connected to the first driving member 4 and the second driving member 5. Only when the photoelectric sensor 12 detects that a beam body 6 is placed on the sliding base 1, can the first driving member 4 and the second driving member 5 be controlled to start at this time, and then the beam body 6 is transported. When the beam body 6 is not detected, the first driving member 4 and the second driving member 5 are turned off to avoid the driving members doing useless work, thereby achieving the effect of energy conservation.
[0040] As Figure 3 shown in the figure, in the walking jacking and sliding equipment provided in this embodiment, on both sides of the sliding base 1, there are respectively provided bottom plates 13 extending outwards. The bottom plates 13 have avoidance holes 14 for passing through fasteners. The fasteners can be bolts. After the bolts pass through the avoidance holes 14, they are threadedly connected to the precast site, so that the sliding base 1 is stably installed. Additionally, as an alternative implementation, the bottom plates 13 can be omitted, and through holes penetrating up and down are opened on the body of the sliding base 1. After the bolts pass through the through holes, they are threadedly connected to the precast site.
[0041] As Figure 3 、 Figure 4 shown in the figure, in the walking jacking and sliding equipment provided in this embodiment, displacement sensors 15 are respectively provided on the first driving member 4 and the second driving member 5. The displacement sensors 15 are electrically connected to the control box 16, and the control box 16 is electrically connected to the first driving member 4 and the second driving member 5. The displacement sensors 15 can measure the moving distances of the first driving member 4 and the second driving member 5 and feedback them to the control box 16, so that the control box 16 can accurately control the movement of the first driving member 4 and the second driving member 5.
[0042] As Figure 2 shown in the figure, in the walking jacking and sliding equipment provided in this embodiment, it further includes: a lifting plate 17, which is installed at the driving end of the second driving member 5. The second driving member 5 drives the beam body 6 to move up and down through the lifting plate 17. The lifting plate 17 can increase the contact area with the beam body 6 and can disperse the concentrated stress, thereby avoiding the situation that the beam body 6 and the second driving member 5 are damaged due to excessive concentrated stress.
[0043] As Figure 2 shown in the figure, in the walking jacking and sliding equipment provided in this embodiment, the lifting plate 17 is detachably installed at the driving end of the second driving member 5 through fasteners. The lifting plate 17 has through holes. The fasteners can be bolts. After the bolts pass through the through holes, they are threadedly connected to the driving end of the second driving member 5. The lifting plate 17 is detachable, which is convenient to change the size of the lifting plate 17 according to the size of different beam bodies 6, and has a wider application range. Additionally, as an alternative implementation, the lifting plate 17 can also be welded to the driving end of the second driving member 5.
[0044] The method for using the walking type pushing and sliding device provided in this embodiment is as follows:
[0045] First, place the beam 6 on the lifting plate 17. At this time, the beam 6 blocks the light, and the light sensor cannot detect the light, so the restrictions on the first drive member 4 and the second drive member 5 are released. At this time, the worker operates the control box 16, and the first drive member 4 drives the sliding box 2 to move, driving the beam 6 to move horizontally, and the second drive member 5 drives the beam 6 to move up and down. After the beam 6 moves to the specified position, the sliding box 2 can be restored to its original position.
[0046] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present utility model.
