Description

Technical Field

[0001] This utility model relates to the technical field of road sampling equipment, specifically to an electric self-loading and unloading road drilling and coring machine. Background Technology

[0002] Core sampling of highway pavements is a crucial method for inspecting the formation of the base course, the thickness of the surface layer, and the degree of compaction. Core sampling machines are frequently used in new construction, maintenance, and road condition surveys, but several problems have emerged during their use. Firstly, due to different sampling locations, the core sampling machine needs to be moved multiple times. The machine typically weighs around 200 kg, and manual unloading requires multiple inspectors working simultaneously. With a high number of core samplings per day, workers are prone to fatigue, and manual unloading poses significant safety risks. Secondly, if a small lifting device or other lifting mechanism is installed on the transport vehicle, this method requires fixing and modifying the vehicle. When the transport vehicle is used for other purposes, its loading capacity is reduced, and modifications must comply with relevant national laws and regulations. If the core sampling machine is made into a towable type with wheels added directly to the bottom, this method requires securing the core sampling machine inside the truck bed, limiting the transport speed. Utility Model Content

[0003] This utility model addresses the problems mentioned above by designing an electric self-loading and unloading road drilling and coring machine, which improves the convenience of loading and unloading the machine body onto and off vehicles and saves manpower.

[0004] To achieve the above objectives, this utility model provides an electric self-loading road drilling and coring machine, including a coring machine body, a guide wheel frame, a guide rail frame, and a lifting mechanism. The coring machine body is movably connected to the guide rail frame through the lifting mechanism. The guide wheel frame is fixedly installed on the engine side of the coring machine body, and the guide wheel frame is connected to the lifting mechanism through a pin.

[0005] Furthermore, the lifting mechanism includes a power source, a rotating shaft, and a first drive sprocket, a second drive sprocket, a first idler sprocket, and a second idler sprocket that are rotatably connected to the guide rail frame. The housing of the power source is fixedly installed on the guide rail frame. One end of the rotating shaft is fixedly connected to the output shaft of the power source, and the other end is rotatably connected to the guide rail frame through a support base. The power source drives the first drive sprocket and the second drive sprocket respectively through the rotating shaft. A first chain is hung between the first drive sprocket and the first idler sprocket, and a second chain is hung between the second drive sprocket and the second idler sprocket.

[0006] Furthermore, the guide rail frame is symmetrically provided with slide rails, the guide wheel frame is rotatably connected to guide wheels, and the guide wheels are tactilely connected to the slide rails.

[0007] Preferably, multiple sets of guide wheels are arranged in an array along the opening direction of the slide rail.

[0008] Furthermore, the guide rail frame is equipped with a traveling mechanism.

[0009] Furthermore, the walking mechanism includes a first support leg and a second support leg that are slidably connected to the guide rail frame. A first directional wheel and a second directional wheel are installed below the first support leg, and a third directional wheel and a fourth directional wheel are installed below the second support leg.

[0010] Furthermore, the walking mechanism also includes two omnidirectional wheels symmetrically installed below the guide rail frame.

[0011] Furthermore, both ends of the first and second support legs are fixedly connected to limit plates.

[0012] Preferably, the first omnidirectional wheel, the second omnidirectional wheel, the second directional wheel, and the fourth directional wheel are on the same horizontal plane, while the first directional wheel and the third directional wheel are higher than the horizontal plane.

[0013] Furthermore, the guide rail frame is fixedly connected with a handle.

[0014] In summary, this utility model has the following advantages and beneficial technical effects:

[0015] 1. This utility model does not require fixing or modifying the transport vehicle; only a small number of workers are needed to load and unload the coring equipment.

[0016] 2. When a long core sample gets stuck between the drill bit and the ground, there is no need to disassemble the core sampler drill bit. The core sample can be taken out from below by raising the core sampler body using the lifting mechanism. The lifting mechanism is powered by a lithium battery, which has a long battery life and meets the needs of high-frequency detection.

[0017] 3. In this utility model, multiple load-bearing wheels are installed under the guide rail frame, making it more stable during short-distance road movement. Attached Figure Description

[0028] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail as follows:

[0029] like Figures 1-2 As shown in the figure, this embodiment discloses an electric self-loading road drilling core extractor, including a core extractor body 1, a guide wheel frame 2, a guide rail frame 3, and a lifting mechanism 4. The core extractor body 1 includes a support, a small internal combustion engine, an automatic water pump, a drill bit, a ball screw lifting assembly, and a sturdy column. The guide wheel frame 2 is fixedly installed on the engine side of the core extractor body 1, and the guide wheel frame 2 is fixedly connected to the lifting mechanism 4 through a pin 5, so that the guide rail frame 3 is movably connected to the core extractor body 1 through the lifting mechanism 4.

[0030] like Figure 3As shown, the lifting mechanism 4 includes a power source 41, a rotating shaft 42, and symmetrically arranged and rotatably connected drive sprocket 1 43, drive sprocket 2 44, idler sprocket 1 45, and idler sprocket 2 46 to the guide rail frame 3. The power source 41 adopts a dual-axis output servo motor reducer, wherein the reducer housing is fixedly installed on the guide rail frame 3. In this embodiment, there are two sets of rotating shafts 42, one end of which is fixedly connected to the output shaft of the power source 41 through a coupling, and the other end is rotatably connected to the guide rail frame 3 through a support base 47. The power source 41 drives the drive sprocket 1 43 and drive sprocket 2 44 respectively through the rotating shaft 42. A chain 1 48 is hung between drive sprocket 1 43 and idler sprocket 1 45, and a chain 2 49 is hung between drive sprocket 2 44 and idler sprocket 2 46. The power source 41 is driven by a lithium battery power module and a drive circuit to achieve forward and reverse rotation. The forward and reverse rotation of the motor is existing technology and will not be described in detail here. The two ends of the guide wheel frame 2 are fixedly connected to the first chain 48 and the second chain 49 respectively through the pin shaft 5.

[0031] like Figures 4-5 As shown, the guide rail frame 3 is symmetrically provided with slide rails, and the guide wheel frame 2 is rotatably connected to the guide wheel 21, which is rolled within the slide rail. In this embodiment, there are two sets of guide wheels 21 arranged linearly along the opening direction of the slide rail. The guide rail frame 3 is provided with a through slot and a traveling mechanism 6 is installed at the bottom. The traveling mechanism 6 includes a first support leg 61 and a second support leg 62. Under the constraint of the through slot, the first support leg 61 and the second support leg 62 slide horizontally based on the guide rail frame 3. A first directional wheel 63 and a second directional wheel 64 are installed below the first support leg 61. Below the second caster wheel 64 and the second support leg 62, there are three directional casters 65 and four directional casters 66; both ends of the first support leg 61 and the second support leg 62 are welded with limit plates 69, which cover and block the through slots; the first caster wheel 67, the second caster wheel 68, the second directional caster wheel 64 and the fourth directional caster wheel 66 are on the same horizontal plane, while the first directional caster wheel 63 and the third directional caster wheel 65 are 0.5~1.2cm higher than this horizontal plane; a handle 31 is fixedly installed on the side of the guide rail frame 3 away from the core extractor body 1.

[0032] The working principle of this electric self-loading road drilling and coring machine is as follows:

[0033] Before the core extractor body 1 is transferred onto the vehicle, the traveling mechanism 6 brings it to the vicinity of the transport vehicle. At this time, outrigger 1 61 and outrigger 2 62 are in the front position, and directional wheels 2 64 and directional wheels 4 66 are away from the casters. When loading, the power source 41 is started, and the sprocket and chain drive the core extractor body 1 to rise. The core extractor body 1 is continuously raised until it is higher than the floor of the transport vehicle. The core extractor body 1 is pushed into the vehicle until the guide rail frame 3 is 2cm away from the edge of the vehicle. The power source 41 reverses, lowers the core extractor body 1 to the floor of the vehicle, and then retracts outrigger 1 61 and outrigger 2 62 to the rear position to ensure that the guide rail frame 3 avoids the vehicle during lifting. Then, the guide rail frame 3 is raised until the wheels of the traveling mechanism 6 are higher than the floor of the vehicle. Outrigger 1 61 and outrigger 2 62 are pushed back to the front position, and the core extractor body 1 is raised so that the wheels are supported on the floor of the vehicle. It is then pushed deeper into the vehicle for loading.

[0034] After loading, the core extractor body 1 is lowered to the floor of the truck bed to ensure that the core extractor remains fixed during the transportation of the vehicle.

[0035] When disembarking, raise the core extractor body 1 to ensure that it does not rub against the floor of the carriage during the rearward movement of the equipment. Pull the equipment backward until the back of the guide rail frame 3 is 2cm away from the edge of the carriage. Lower the core extractor body 1 to the floor of the carriage while raising the guide rail frame 3. Retract the outriggers to the rear position to avoid the carriage. Lower the guide rail frame 3. Before the bottom wheels of the guide rail frame 3 touch the ground, push outrigger 1 61 and outrigger 2 62 to the front position. After the guide rail frame 3 touches the ground, raise the core extractor body 1 above the floor of the transport vehicle and pull it backward to complete the disembarkation.

[0036] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
