[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] refer to Figure 1-Figure 6 As shown, the utility model provides a tooling trolley for installing curbstones, which comprises a chassis 1, a plurality of universal balls 6 and a plurality of jacks 7.

[0030] A wheel is installed at each of the four corners of the chassis 1, and a handrail 5 is protruding from one end of the top surface of the chassis 1; specifically, the handrail 5 is arranged at one end in the length direction of the chassis 1. Pushing and pulling the handrail 5 can rotate the wheel, thereby driving the entire tooling trolley to move.

[0031] Multiple universal balls 6 are evenly arranged on the top surface of the chassis 1 to support the curbstones 10 to be installed. Multiple universal balls 6 form the bearing surface of the curbstones 10 to be installed, have outstanding bearing capacity, and have the function of moving and conveying in any direction on the plane, so that the curbstones 10 to be installed placed on the universal balls 6 can be flexibly moved under the action of external force, so that the plane position and posture of the curbstones 10 to be installed can be easily and quickly adjusted.

[0032] A plurality of jacks 7 are evenly arranged on the top surface of the chassis 1, and the top surface of the jacks 7 is lower than the top surface of the universal ball 6. The jacks 7 include a push rod 73, which extends toward the bottom surface of the chassis 1 and penetrates the chassis 1. When the plurality of jacks 7 are working, the plurality of push rods 73 extend out of the bottom surface of the chassis 1 to make the four wheels leave the ground, that is, at this time, the plurality of push rods 73 provide a stable support for the entire tooling trolley, and then the height of the chassis 1 can be adjusted by adjusting the extension length of the push rods 73, that is, the height of the curbstone 10 to be installed can be adjusted. It can be understood that the extension lengths of the push rods 73 on the plurality of jacks 7 are not the same, and specific adjustments are made according to the actual situation when the curbstone is installed.

[0033] Further explanation: when the tooling trolley of this embodiment is used to install the curbstone,

[0034] First, place the tooling trolley in the construction area where the curb 10 is to be installed; it should be noted that two rows of support bolts with adjustable top surface heights have been pre-buried in the ground of the construction area along the extension direction of the entire curb, and the distance between the two rows of support bolts is greater than the width of the tooling trolley chassis 1, but less than the width of the curb 10 to be installed, and the tooling trolley is placed between the two rows of support bolts; it can be understood that at least four support bolts are arranged in the ground of the construction area corresponding to each curb 10 to be installed;

[0035] Then, the curbstone 10 to be installed is placed on the plurality of universal balls 6 of the tooling trolley by using a crane to complete the rough placement of the curbstone 10 to be installed; when placing, it should be noted that the length direction of the curbstone 10 to be installed corresponds to the length direction of the tooling trolley chassis 1, the width direction of the curbstone 10 to be installed corresponds to the width direction of the tooling trolley chassis 1, and the two sides of the width direction of the curbstone 10 to be installed respectively exceed the two sides of the width direction of the tooling trolley chassis 1; then, under the action of external force such as manpower or a horizontal jack, the plane position and posture of the curbstone 10 to be installed on the universal ball 6 are finely adjusted until the curbstone 10 to be installed is aligned with the set-out edge line on the ground, thereby making the curbstone 10 to be installed meet the linear control requirements;

[0036] Then, the multiple jacks 7 on the tooling trolley are activated to extend the push rods 73 out of the bottom surface of the chassis 1 to support the chassis 1 and make the wheels leave the ground; by adjusting the extension length of each push rod 73, the height of the chassis 1 is finely adjusted, that is, the height of the curbstone 10 to be installed is finely adjusted, until the top surface of the curbstone 10 to be installed is aligned with the elevation that has been set out on the middle wall, and the verticality of the curbstone 10 to be installed meets the construction requirements, thereby making the curbstone 10 to be installed meet the elevation control requirements;

[0037] Finally, adjust the top surface heights of the multiple supporting bolts corresponding to the curbstone 10 to be installed so that the top surfaces of the multiple supporting bolts are pressed against the bottom surface of the curbstone 10 to be installed, that is, the multiple supporting bolts can reliably support the curbstone 10 to be installed; the top rod 73 of the jack 7 is retracted, and the height of the chassis 1 is lowered until the wheels touch the ground. At this time, the curbstone 10 to be installed is no longer in contact with the tooling trolley, and the tooling trolley can be easily and quickly moved out of the construction area by pushing and pulling the handrail 5.

[0038] The above-mentioned exemplary embodiment, through the provision of multiple universal balls 6 and multiple jacks 7, enables the tooling trolley to easily adjust the installation height and posture of the curbstone 10 to be installed, thereby reducing the difficulty of installing the curbstone and further improving the installation accuracy and efficiency of the curbstone.

[0039] refer to Figure 2-Figure 6As shown, in some embodiments, the jack 7 further includes a cylinder 71 and a guide sleeve 72. The axial direction of the cylinder 71 is consistent with the axial direction of the push rod 73. The cylinder 71 is connected to the top surface of the chassis 1 by bolts. An oil chamber with an open end is provided in the cylinder 71 along its axial direction, and the guide sleeve 72 is sealed and connected to the open end of the oil chamber. The push rod 73 includes a rod portion and a piston portion that are connected to each other and coaxially arranged. The piston portion is slidably connected in the oil chamber to separate the oil chamber into a first oil chamber and a second oil chamber. The rod portion passes through the guide sleeve 72 and can reciprocate along the axial direction of the cylinder 71, that is, the rod portion can reciprocate relative to the cylinder 71 and the guide sleeve 72. The rod portion and the guide sleeve 72 are dynamically sealed to keep the two sealed. A first oil circuit 75 connected to the first oil chamber and a second oil circuit 77 connected to the second oil chamber are also provided on the wall of the cylinder 71; the end of the first oil circuit 75 away from the first oil chamber and the end of the second oil circuit 77 away from the second oil chamber are also connected to a set of hydraulic devices 9, and the amount of oil in the first oil chamber and the second oil chamber is adjusted by the hydraulic device 9 to drive the piston part to move to drive the rod part to move, thereby adjusting the extension length of the push rod 73.

[0040] refer to Figure 2-Figure 6 As shown, in some embodiments, the hydraulic device 9 is arranged on the chassis 1 and is located below the armrest 5. A first joint 74 communicating with the first oil circuit 75 and a second joint 76 communicating with the second oil circuit 77 are convexly provided on the wall of the cylinder 71. One end of the first joint 74 away from the cylinder 71 and one end of the second joint 76 away from the cylinder 71 are respectively connected to the hydraulic device 9 through hydraulic pipes 8, thereby realizing the connection between the jack 7 and the hydraulic device 9.

[0041] refer to Figure 2-Figure 3 As shown, in some embodiments, the universal ball 6 includes a ball seat and a sphere. The sphere is universally rotatably connected in the ball seat, and the spherical surface of the sphere protrudes from the top surface of the ball seat. The bottom surface of the ball seat is connected to the top surface of the chassis 1, and the bottom surface of the curb 10 to be installed is pressed onto the spherical surface of the sphere.

[0042] refer to Figure 2-Figure 3 As shown, in some embodiments, the number of jacks 7 is four, and the number of universal balls 6 is eight; two universal balls 6 are symmetrically arranged on both sides of each jack 7; thereby, the jacks 7 and universal balls 6 are matched with each other on the chassis 1, and the curbstone 10 to be installed can be placed in a balanced manner.

[0043] refer to Figure 2-Figure 4As shown, in some embodiments, among the four wheels, the two wheels on the side close to the handrail 5 are universal wheels 2, and the two wheels on the side away from the handrail 5 are fixed wheels 3; by arranging the universal wheels 2 on the side of the handrail 5, it is convenient to adjust and control the moving direction of the tooling trolley. In some embodiments, at least one universal wheel 2 is installed with a brake device 4; before adjusting the curb 10 to be installed on the tooling trolley, the universal wheel 2 needs to be locked by the brake device 4, thereby locking the position of the tooling trolley to prevent the tooling trolley from moving when the curb 10 to be installed is adjusted, thereby affecting the adjustment accuracy and efficiency of the curb 10 to be installed.

[0044] refer to Figure 2-Figure 4 As shown, in some embodiments, a mounting groove is provided through the chassis 1 corresponding to each fixed wheel 3, and the size of the mounting groove is larger than the outer diameter of the fixed wheel 3; a bracket is convexly provided on the top surface of the chassis 1 on both sides of the mounting groove, and the two brackets are provided with shaft holes adapted to the wheel axles of the fixed wheels 3; the fixed wheels 3 are inserted into the mounting grooves, and the two ends of the wheel axles of the fixed wheels 3 are rotatably connected to the shaft holes of the two brackets. Usually, the wheel diameter of the universal wheel 2 is larger than the wheel diameter of the fixed wheel 3, and the chassis 1 on one side of the universal wheel 2 can be set to be a step-shaped folded upward to free up the installation space of the universal wheel 2. This exemplary embodiment reduces the height difference between the bottom surface of the chassis 1 and the ground contact end of the wheel, thereby reducing the overall adjustable height of the top rod 73 of the jack 7, and it is not necessary to use a large-sized jack 7.

[0045] In summary, the tooling trolley for curbstone installation of the utility model has the ability to easily adjust the installation height and posture of the curbstone to be installed, which can reduce the difficulty of curbstone installation and thus improve the curbstone installation efficiency.

[0046] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
