Description

Technical Field

[0001] This application relates to the field of coring machine technology, and in particular to a vehicle-mounted coring machine for road engineering. Background Technology

[0002] Road surface core sampling is a key technical means to assess the quality of road construction, analyze the causes of road defects, and formulate maintenance plans. On-site core sampling operations mainly rely on independent core sampling equipment, commonly including push-type core sampling machines and handheld core sampling machines.

[0003] The aforementioned traditional equipment has some problems in practical applications. It lacks operational mobility and has long auxiliary time. Each time a sample is taken, the operator has to move the heavy core sampling host, water tank and other equipment from the transport vehicle. The whole process is time-consuming and labor-intensive. This repetitive loading, unloading, handling and fixing work greatly reduces the overall operation efficiency and increases the labor intensity of the operators. Utility Model Content

[0004] To address the significant shortcomings in operational mobility and preparation efficiency, this application provides a vehicle-mounted coring machine for road engineering.

[0005] The technical solution of the vehicle-mounted coring machine for road engineering provided in this application is as follows:

[0006] A road construction vehicle-mounted core sampling machine includes two parallel carriages arranged on a mobile carriage. Each carriage has a sliding opening along its length, and a flip-positioning component is slidably fitted inside each sliding opening. Pin holes are formed on the outer walls of both ends of the carriages, and the two pin holes respectively form a locking engagement with the flip-positioning component in a horizontally stowed state and a vertically working state. A lateral adjustment mechanism is fixed between the two flip-positioning components. The lateral adjustment mechanism includes a crossbeam and a slide seat slidably mounted on the carriage. A vertical feeding mechanism is installed on one side of the slide seat. The vertical feeding mechanism includes two vertical slide rails connected to the slide seat. A feeding module is slidably mounted on the vertical slide rails, and a core sampling assembly is installed at the bottom of the feeding module.

[0007] Preferably, the flipping positioning component includes a U-shaped plate sleeved on the outside of the slide, with rotating shafts fixed at both ends of the U-shaped plate inside the slide opening, and positioning pins adapted to pin holes provided on the outside of the U-shaped plate, and the U-shaped plate is fixedly connected to the outer wall of the cross frame.

[0008] Preferably, the crossbar is provided with a transverse sliding groove, and the slide block is slidably installed in the transverse sliding groove.

[0009] Preferably, a lateral locking element is provided between one side of the slide and the crossbar.

[0010] Preferably, the transverse locking member includes a side block fixed to the outside of the slide block, a locking bolt is threadedly installed on the side block, and a locking groove is provided on the outside of the cross frame to abut and press against the end of the locking bolt.

[0011] Preferably, the feeding module includes a sliding sleeve slidably disposed on two vertical slide rails, a vertical frame fixed between the two sliding sleeves, a handle fixed on one side of the vertical frame, a locking pin provided on the sliding sleeve, a locking hole for locking and engaging with the locking pin on the outer side of the top of the vertical slide rail, and the core extraction assembly mounted on the vertical frame.

[0012] Preferably, the core-taking assembly includes a core-taking motor fixed on a vertical frame, and the output shaft of the core-taking motor is equipped with a detachable core drill bit.

[0013] Preferably, a support member is fixed on the side of the cross frame away from the slide block. The support member includes an extension plate connected to the cross frame. Two symmetrically arranged support columns slide through the extension plate. A top ring is fixed at one end of each support column, and a support block is fixed at the other end. A spring sleeved on the support column is provided between the support block and the extension plate.

[0014] In summary, the beneficial technical effects of this application are as follows:

[0015] This utility model of a vehicle-mounted coring machine integrates a horizontal adjustment mechanism, a vertical feeding mechanism, a coring assembly, a carriage, and a tilting positioning component onto a mobile carriage. This effectively overcomes the drawbacks of traditional independent coring machines, such as cumbersome loading and unloading and low efficiency in preparatory work before coring operations. The equipment can quickly switch between "horizontal storage" and "vertical operation" modes, significantly reducing coring time and lowering the labor intensity of operators.

[0023] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0024] This application discloses a vehicle-mounted coring machine for road engineering.

[0025] Reference Figure 1 and Figure 2 A road construction vehicle-mounted core sampling machine includes two parallel carriages 1, a tilting and positioning component 4, a lateral adjustment mechanism 5, a vertical feeding mechanism 6, and a core sampling assembly 7. The two carriages 1 are fixedly installed on the floor of a mobile vehicle (such as a pickup truck or engineering vehicle cargo box) by bolts or welding. The installation spacing is determined according to the width of the core sampling assembly 7 to ensure overall stability.

[0026] Reference Figure 1 , Figure 2 Each carriage 1 has a long strip-shaped metal component as its main body, and a long strip-shaped sliding opening 2 is opened on its side along the length direction. The sliding opening 2 provides sliding and rotation space for the rotating shaft 41 of the flip positioning component 4. A pin hole 3 is opened on the outer wall of the carriage 1 near the head and tail of the carriage respectively.

[0027] The positions of the two pin holes 3 correspond to the vertical working state and the horizontal storage state of the core extraction component 7, respectively. The flip positioning component 4 is slidably sleeved in the sliding opening 2, and through the positioning pin 43 and the pin holes 3 at different positions, the entire core extraction component 7 is fixed and its posture is locked.

[0028] Reference Figure 2 and Figure 3 The flipping positioning component 4 includes a U-shaped plate 42 that straddles the outside of the carriage 1. A pivot 41 is inserted into the inside of the U-shaped plate 42 and passes through the slide opening 2 of the carriage 1, so that the entire U-shaped plate 42 and its connected components can slide longitudinally along the slide opening 2 and can be flipped around the central axis of the pivot 41. A manually operable positioning pin 43 (such as a manual pin) is installed on the outer plate of the U-shaped plate 42.

[0029] When locking is required, insert the positioning pin 43 into the corresponding pin hole 3 on the slide 1 to prevent the U-shaped plate 42 from sliding and flipping, thus achieving reliable fixation.

[0030] Reference Figure 1 , Figure 2 Between the outer sides of the U-shaped plates 42 of the two flipping positioning parts 4, a lateral adjustment mechanism 5 is fixedly connected. The lateral adjustment mechanism 5 includes a crossbeam 51 connected to the two U-shaped plates 42. A lateral groove 52 is provided on the crossbeam 51 along the direction perpendicular to the length of the slide 1.

[0031] The slide block 53 is fitted into the transverse slide groove 52 by the protrusion or slider at its bottom, so that it can move smoothly in the transverse direction along the crossbeam 51, thereby realizing the position adjustment of the core drill bit 72 in the transverse direction.

[0032] Reference Figure 2 and Figure 3 To lock the lateral position of the slide block 53, a lateral locking member 8 is provided between one side of the slide block 53 and the cross frame 51. The lateral locking member 8 includes a side block 81 fixed on the outside of the slide block 53. A locking bolt 82 is vertically threaded onto the side block 81. On the outer side surface of the cross frame 51 corresponding to the lateral slide groove 52, a long strip-shaped locking groove 83 parallel to the lateral slide groove 52 is provided.

[0033] After the slide block 53 moves to the predetermined lateral position, tighten the locking bolt 82 so that its end presses firmly against the groove wall of the locking groove 83. The friction generated will firmly position the slide block 53 on the cross frame 51 to prevent lateral movement during the core extraction operation.

[0034] Reference Figure 2 and Figure 4 The vertical feed mechanism 6 is mounted on the slide block 53 and is used to realize the vertical feed of the core extraction operation. It includes two vertical slide rails 61 welded vertically to the slide block 53. Each of the two vertical slide rails 61 is fitted with a sliding sleeve 62 that can slide up and down along it. The two sliding sleeves 62 are fixedly connected to a vertical frame 63 by bolts to form a stable overall lifting platform. A handle 64 is welded or bolted to one side of the vertical frame 63. A locking pin 65 (such as a quick-release pin) is inserted into each sliding sleeve 62. Locking holes corresponding to the locking pins 65 are spaced apart on the outer side of the top of the vertical slide rails 61. When it is necessary to lift and fix the vertical frame 63 at a high position, the locking pins 65 can be inserted into the locking holes at the corresponding height to realize the mechanical locking of the vertical position.

[0035] The operator can slide the vertical frame 63 and the sliding sleeve 62 along the vertical slide rail 61 by using the handle 64, which makes it easy for the operator to manually apply downward pressure or lifting force, thus facilitating the core extraction work.

[0036] Reference Figure 2 and Figure 4 The core sampling assembly 7 is installed at the bottom of the vertical frame 63, including a core sampling motor 71 that is bolted to the vertical frame 63. The output shaft of the core sampling motor 71 extends downward and is fitted with a core sampling drill bit 72 through a quick-change interface (such as a threaded connection or a flange connection).

[0037] The core drill bit 72 can be replaced according to the road surface material and sampling specifications. The core motor 71 provides the core drill bit 72 with high-speed rotation power to cut the road surface.

[0038] Reference Figure 2 and Figure 5 To further enhance the stability of the crossbeam 51 and the car body during operation, a support member 9 is fixed on the side of the crossbeam 51 away from the slide block 53. The support member 9 includes an extension plate 91 welded perpendicularly to the crossbeam 51. Two symmetrically arranged support columns 92 are inserted into the extension plate 91 perpendicularly to the plate surface. The upper end of the support column 92 is fixed with a top ring 93 to prevent it from falling out, and the lower end is fixed with a support block 95 (a rubber pad can be attached to the bottom surface to increase friction). A spring 94 is sleeved on the support column 92, and the spring 94 is located between the support block 95 and the extension plate 91.

[0039] When the core extraction assembly 7 is flipped to the vertical working state, the support member 9 rotates accordingly. The support block 95 at the bottom of the support column 92 abuts against the car floor. At this time, the spring 94 is compressed, thereby continuously providing an upward elastic preload. This force, together with the slide 1, forms a stable support structure after the U-shaped plate 42 is flipped and locked.

[0040] The implementation principle of a road engineering vehicle-mounted coring machine according to an embodiment of this application is as follows:

[0041] When road surface core sampling is required, follow these steps until... Figure 2 The working status shown:

[0042] Unlocking and flipping: Pull out the positioning pin 43, slide the flipping positioning piece 4 to the end of the carriage 1 near the head of the carriage (the pin hole 3 corresponds to the vertical state at this position), slide the entire core-taking mechanism along the sliding opening 2 to the open area at the rear of the carriage, and then use the handle 64 to make the entire mechanism flip around the pivot 41 to the outside of the rear of the carriage until it is completely vertical. When the mechanism is vertical, insert the positioning pin 43 to firmly lock the mechanism in the vertical working posture.

[0043] Lateral and vertical positioning: Loosen the locking bolt 82 of the lateral locking member 8, push the handle 64, and drive the core drill bit 72 to move laterally through the slide block 53, so that it is aligned with the center of the predetermined sampling point on the road surface. After alignment, immediately tighten the locking bolt 82 to lock laterally; then, pull the locking pin 65 upward to release the lock on the vertical slide rail 61, and press down the vertical frame 63 through the handle 64 so that the core drill bit 72 lightly touches the road surface; start the core motor 71, and the core drill bit 72 begins to rotate. The operator continuously and steadily presses down the vertical frame 63 through the handle 64 to drive the core drill bit 72 to drill vertically downward to the road surface. Cooling water can be provided by the assistant by hand-held water hose, which is connected to the vehicle's water tank.

[0044] Sampling and resetting: After drilling to the predetermined depth, keep the drill bit rotating and slowly pull it out. Use a special tool to remove the core sample from the core drill bit 72.

[0045] When the equipment needs to be moved or idle, the entire core-taking assembly 7 is in a stowed state: First, pull out the positioning pin 43 on the flipping positioning piece 4, and flip the horizontal adjustment mechanism 5, the vertical feeding mechanism 6 and the core-taking assembly 7 as a whole around the rotating shaft 41 upward (relative to the front of the vehicle) so that it is placed flat in the carriage; then, slide the flipping positioning piece 4 along the sliding opening 2 to the end of the carriage 1 near the rear of the carriage, and insert the positioning pin 43 into the corresponding pin hole 3 to lock it, so that the mechanism is close to the front or rear of the carriage, saving cargo space to the maximum extent and facilitating transportation and storage.

[0046] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
