Description
Technical Field
[0001] The utility model relates to the technical field of pavement compressive strength test equipment, and more specifically, to a walking and loading device for a pavement core drill machine. Background Art
[0002] Core drill machines are mainly used for core sampling of cement concrete, asphalt concrete, and limestone foundations of highways, airports, ports, docks, dams, etc. for compressive and flexural tests. The maximum core sampling depth can generally reach 600 mm.
[0003] In road construction projects, in order to master the thickness of the pavement structure layer, core sampling operations are usually required. As a special core sampling device, core drill machines are widely used in road construction projects because the core samples taken by them have smooth surfaces and standard sizes.
[0004] Core sampling operations usually need to be carried out at the construction site of the completed highway. This requires transporting the core drill machine in the laboratory to the construction site. Usually, a pickup truck is used as the transportation vehicle for the core drill machine. During the transportation of the existing core drill machine, usually at least four workers are required to lift the core drill machine into the carriage of the pickup truck, and then manually lift it down from the pickup truck when arriving at the site. This is time-consuming and laborious, and consumes a large amount of labor. Safety accidents are likely to occur when the attention is not concentrated, injuring the operating workers.
[0005] Therefore, how to provide a device that can realize the automatic walking and loading of the core drill machine, reducing the input of labor and the occurrence of safety accidents, is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model
[0006] In view of this, the utility model provides a walking and loading device for a pavement core drill machine, aiming to solve the above technical problems.
[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0008] A walking and loading device for a pavement core drill machine is installed in the carriage of a pickup truck and includes:
[0009] A fixed rod, the two ends of which are respectively fixed to the opposite side walls of the front part of the carriage of the pickup truck;
[0010] A winch, the base of which is fixed in the middle of the fixed rod, and the drive motor of the winch is electrically connected to the power system of the pickup truck;
[0011] A track, one end of which abuts against the side of the tail of the pickup truck, and the other end abuts against the ground;
[0012] Among them, the walking wheels of the core drill are in rolling connection with the track, and the steel wire rope of the winch is fixedly tied to the frame of the core drill.
[0013] The beneficial effect of the above technical solution is that the core drill is firmly tied by the steel wire rope of the winch. After the winch motor is started, the winch winds up the steel wire rope, which can pull the core drill along the track onto the carriage of the pickup truck, realizing the automatic walking and boarding of the core drill. When it is necessary to unload the core drill from the vehicle, the winch relaxes the steel wire rope, and the core drill is slowly walked off the vehicle by the relaxation of the steel wire rope.
[0014] Preferably, the track is a channel steel, and the walking wheels roll in the groove of the channel steel. The walking wheels of the core drill can be clamped by the two side walls of the channel steel to ensure the stability of the core drill during the process of getting on and off the vehicle.
[0015] Preferably, the track includes a first channel steel and a second channel steel, and the end of the first channel steel is hinged to the end of the second channel steel through a first hinge. The track can be folded through the first hinge, which is convenient for storage and transportation.
[0016] Preferably, a handle is fixed on the outer wall of the track. The handle is convenient for taking the track.
[0017] Preferably, it further includes a guiding plate. One end of the guiding plate is hinged to the end of the track close to the vehicle side, and the panel of the guiding plate abuts against the upper surface of the vehicle side. The guiding plate can realize the guiding of the core drill onto the vehicle and prevent damage to the vehicle side.
[0018] Preferably, the guiding plate is hinged to the track through a second hinge. The guiding plate and the track can be folded, reducing the occupied space and being convenient for transportation and storage.
[0019] Preferably, a clamping block is fixed at the end of the guiding plate away from the track. The clamping block is bent at 90 degrees with the guiding plate and is clamped in the gap between the vehicle side and the tail of the carriage. The clamping block is clamped at the gap between the vehicle side and the tail of the carriage, which can better fix the track and prevent displacement during use.
[0020] Preferably, the guiding plate is made of iron sheet, and a pressing plate is fixed at the end of the guiding plate away from the track. The pressing plate is on the same horizontal plane as the guiding plate. The guiding plate is made of iron sheet, which is convenient for obtaining materials and has low cost. Since the iron sheet has toughness, in order to prevent the guiding plate from warping during use, the guiding plate is pressed against the upper surface of the vehicle side by the pressing plate.
[0021] Preferably, a wedge block is provided at the contact between the track and the ground. This can prevent the track from shifting during the walking process of the core drill on the track and causing safety accidents.
[0022] Preferably, the traveling wheels of the core drill are rubber wheels with a diameter of not less than 15 cm. The use of rubber traveling wheels increases the friction between them and the track. Increasing the diameter of the traveling wheels enables the core drill to move along the track more easily and reduces the load on the winch.
[0023] As can be seen from the above technical solutions, compared with the prior art, the present utility model discloses a traveling and boarding device for a road surface core drill. It is guided by a track and pulled by a winch to realize the automatic boarding and alighting of the core drill. The transfer work of the core drill can be achieved by a single operator, reducing the labor input. Moreover, it is simple to manufacture, convenient to obtain materials, and has a low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] A track 4, one end of the track 4 abuts against the side of the pickup truck tail, and the other end abuts against the ground;
[0035] Wherein, the walking wheels of the coring machine 12 are in rolling connection with the track 4, and the steel wire rope 3 of the winch 2 is fixedly tied to the frame of the coring machine 12.
[0036] In this embodiment, by winding the steel wire rope by the cigarette machine, the coring machine can be pulled onto the pickup truck along the track, which can be realized by single-person operation.
[0037] In order to further optimize the above technical solution, the track 4 is a channel steel, and the walking wheels roll in the groove of the channel steel. The two side walls of the channel steel can be used as baffles. The walking wheels of the coring machine walk along the groove of the channel steel, and the getting on and off of the coring machine is more stable.
[0038] In order to further optimize the above technical solution and facilitate the storage and transportation of the track, the track 4 includes a first channel steel 41 and a second channel steel 42, and the end of the first channel steel 41 is hinged to the end of the second channel steel 42 through a first hinge 5.
[0039] The first channel steel and the second channel steel can be folded relative to the first hinge. The track can be folded up for storage when not in use. After the coring machine gets on the vehicle along the track, the track can be folded up and installed in the carriage of the pickup truck and transported to the coring site together with the coring machine. The track is used to guide the coring machine to get off the vehicle at the site.
[0040] In order to further optimize the above technical solution and facilitate the taking of the track, a handle 6 is fixed on the outer wall of the track 4.

[0042] The guiding plate can pad the gap at the connection between the side and the carriage, preventing the coring machine from being unstable due to bumps when walking to the connection between the side and the carriage.
[0043] In order to further optimize the above technical solution and facilitate the transportation and storage of the guiding plate, the guiding plate 7 is hinged to the track 4 through a second hinge 11.
[0044] To further optimize the above technical solution and ensure the stability of the track during use, a clamping block 8 is fixed to the end of the guide plate 7 away from the track 4. The clamping block 8 is bent at a 90-degree angle with the guide plate 7 and is clamped in the gap between the car body and the tail of the carriage.
[0045] In some other specific embodiments, the guide plate is made of iron sheet.
[0046] To further optimize the above technical solution and prevent the guide plate made of iron sheet from warping upwards and pressing the guide plate against the car body, a pressing plate 9 is fixed to the end of the guide plate 7 away from the track 4. The pressing plate 9 and the guide plate 7 are on the same horizontal plane.
[0047] To further optimize the above technical solution and improve the stability performance of the track during use, a wedge block 10 is provided at the contact between the track 4 and the ground.
[0048] In this embodiment, the traveling wheels of the core drill 12 are rubber wheels, and the diameter of the rubber wheels is not less than 15 cm. Preferably, it is 20 cm.
[0049] Currently, the traveling wheels of the core drills commonly used in the market during traveling are all iron rollers with a diameter of about 5 cm. The present utility model increases the diameter of the traveling wheels of the core drill and uses rubber material, which increases the friction between the traveling wheels and the channel steel, ensures the safety factor during the process of the core drill getting on and off the vehicle, prevents the hard connection between the iron rollers and the channel steel, and increasing the diameter of the traveling wheels can make it more convenient for the core drill to move.
