Description

Technical Field

[0001] The utility model relates to the technical field of cross-height transportation, and more specifically, to a cross-height transportation device. Background Art

[0002] The coring machine is one of the important tools for detecting the quality of the road surface. By collecting core samples with the coring machine and analyzing them, the thickness, density, strength and other parameters of the road surface can be determined. During the construction process, the quality of the road surface can be understood at any time by coring. The frequency of use of coring machines in highway projects is relatively high, but traditional coring machines are relatively bulky, generally about 120cm in length, about 80cm in width, about 130cm in height, and weighing about 190kg. They are usually equipped with pickup trucks for transportation, or light trucks for transportation; during transportation, frequent loading and unloading are required. This cross-height transportation is time-consuming and labor-intensive, and the labor intensity is high. In order to reduce the labor intensity, some lifting devices are usually used to transport the coring machine across heights.

[0003] The utility model patent with the authorization announcement number CN211995720U discloses a hydraulic lifting plate for a loading platform for building materials processing, including a base, a hydraulic cylinder is fixedly installed on the upper end of the base, a connecting sleeve is installed on the upper end of the hydraulic rod of the hydraulic cylinder, a lifting plate is fixedly connected to the upper end of the connecting sleeve, a ball groove is opened on the upper end of the lifting plate, a steel ball is installed in the ball groove, a retaining edge is fixedly connected to the upper end of the lifting plate, a cargo box is placed on the upper end of the steel ball, and a retaining rod is connected to the left side of the lifting plate through a thread. The utility model installs a hydraulic cylinder on the base, a connecting sleeve is installed on the hydraulic rod of the hydraulic cylinder, and a lifting plate is designed on the upper end of the connecting sleeve. The height of the lifting plate can be adjusted by lifting the lifting plate, which is convenient for adjustment during loading, and a guide sleeve is designed on the base, and a guide column fixedly connected to the lifting plate is installed in the guide sleeve, so that the lifting process is more stable.

[0004] The above scheme is a common lifting device for cross-height transportation. By raising, the items to be transported can be transported from a low place to a high place, and by lowering, the items to be transported can be transported from a high place to a low place. In practice, after the items are transported to a low place or a high place by the lifting device, they usually need to be transferred for a certain distance so that the items can reach the designated use position or placement position. At present, the items are transferred from the lifting device to a trolley, and the trolley is used to push the items to achieve the transfer after reaching a high place or a low place. However, it is very inconvenient to transfer the items from the lifting device to the trolley, especially for some heavy items, such as coring machines. It usually takes three or four people to transfer them from the lifting device to the trolley, which is time-consuming and labor-intensive, and the transportation efficiency is low. Utility Model Content

[0005] The utility model aims to overcome at least one defect of the above-mentioned prior art and provide a cross-height transport equipment for solving the technical problem that heavier items need to be transferred to a trolley for transportation after being transported to a high or low place, and such transfer is time-consuming and labor-intensive, and the transportation efficiency is low.

[0006] The technical solution adopted by the utility model is a cross-height transportation equipment, including a lifting device and a load-bearing trolley; the lifting device has a lifting platform that can move up and down; the load-bearing trolley includes a body and moving wheels installed on the body, the body can be installed on the lifting platform in a linearly movable manner, and when the lifting platform is lowered to the lowest point, the distance from the bottom side of the moving wheel of the load-bearing trolley to the top side of the lifting device is greater than the distance from the bottom side of the lifting device to the top side of the lifting device.

[0007] First, control the lifting platform to descend to the lowest position, and move the coring machine onto the carrying trolley. At this time, the lifting device is suspended below the carrying trolley. Then, the coring machine and the lifting device are moved to the rear of the carriage of the transport vehicle by the carrying trolley and stop. Then, control the lifting platform to rise, and the carrying trolley and the coring machine are lifted up together by the lifting device. When the bottom side of the moving wheel of the coring machine is flush with the surface of the carriage, stop. Then, the coring machine is moved from the lifting platform to the carriage by the carrying trolley. The lower part of the lifting device is located outside the carriage, and the lifting platform is connected to the carrying trolley. At this time, the carrying trolley is fixed in the carriage and moved to the carriage by the lifting device. The lifting device is controlled to descend and folded up to a level above the plane of the carriage, and then moved to the bottom of the carrying trolley in the carriage. Finally, the coring machine and the lifting device are moved to the designated placement position in the carriage by the carrying trolley and fixed, and loading is completed; when unloading, the reverse operation is sufficient; after the coring machine is transported to a high or low place through this solution, there is no need to transfer to other equipment. The loading and unloading of the coring machine and the transfer after loading and unloading can be completed by one person, which saves time and effort, can effectively improve handling efficiency, and reduce labor costs; this solution only takes the coring machine as an example, and other heavier items are also applicable.

[0008] Furthermore, roller grooves are provided on both sides of the lifting platform, rollers corresponding to the roller grooves are provided on both sides of the vehicle body, and the rollers are rollingly matched with the corresponding roller grooves. The rolling match between the rollers and the roller grooves has small friction, is more convenient to move, and has low manufacturing and maintenance costs; the lifting platform can also be slidably connected to the vehicle body through a ball slide rail, which has small friction and higher stability.

[0009] Furthermore, the vehicle body is a U-shaped structure, the rollers are arranged on two opposite side end surfaces of the vehicle body, and the roller grooves are arranged on two opposite side end surfaces of the lifting platform. The U-shaped structure can save more materials, effectively reduce costs, and make it easier to observe the situation of the lower lifting device. At the same time, it can be connected to both sides of the lifting platform and connected together with the two opposite side end surfaces of the lifting platform in a rolling manner, so that the stability during movement is higher.

[0010] Furthermore, the lifting platform is in a U-shaped structure, and the vehicle body is sleeved on the lifting platform from top to bottom.

[0011] Furthermore, the vehicle body is provided with reinforcing ribs, which are used to connect the two sides of the open end of the vehicle body. The reinforcing ribs can effectively improve the structural strength of the vehicle body, making it more load-bearing and less prone to deformation.

[0012] Furthermore, the cross-height transport equipment also includes a locking assembly, and the vehicle body is fixedly connected to the lifting platform through the locking assembly. When the load-bearing trolley needs to be moved into the carriage after being raised, the locking assembly is opened to push the load-bearing trolley; when the load-bearing trolley is moved after being lowered, the lifting platform and the vehicle body are locked together through the locking assembly to prevent the load-bearing trolley and the lifting platform from relative movement. The locking assembly makes it easier for the load-bearing trolley and the lifting device to move relative to each other and to be fixed in combination.

[0013] Furthermore, the lock assembly comprises a U-shaped latch, an insertion port arranged on the lifting platform and an insertion hole arranged on the vehicle body, and two legs of the U-shaped latch can be respectively inserted into the insertion hole and the insertion port. The lock assembly has a simple structure, low cost and is easy to use.

[0014] Furthermore, the moving wheels are provided in plurality on the vehicle body, and at least one of the moving wheels has a locking function. The moving wheels with a locking function are mainly used to fix the coring machine, firstly to prevent the coring machine from being displaced due to the shaking of the vehicle body after loading; secondly to prevent the coring machine from being displaced due to the vibration of the engine during coring operation, so as to fix the coring position.

[0015] Furthermore, the lifting device also includes a base, a scissor frame and a power telescopic component. The two legs at the front end of the bottom of the scissor frame are movably connected to the base, the two legs at the rear end of the bottom of the scissor frame are rotatably connected to the base, the two legs at the front end of the top of the scissor frame are movably connected to the lifting platform, the two legs at the rear end of the top of the scissor frame are rotatably connected to the lifting platform, the power telescopic component is rotatably installed on the base, and the telescopic end of the power telescopic component is rotatably connected to the central axis of the scissor frame. After folding, the thickness of this scissor frame can be minimized, so that it can be suspended and hidden under the carrying trolley.

[0016] Furthermore, the power telescopic component is an electric hydraulic rod. The electric hydraulic rod has the characteristics of large load capacity, sensitive action, stable operation, and low energy consumption, and is suitable for heavier objects, such as a coring machine.

[0023] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0024] like Figure 1-4 As shown, the present solution discloses a cross-height transportation device, including a lifting device 1, a carrying trolley 2 and a locking assembly 8.

[0025] like Figure 3 As shown, the lifting device 1 has a lifting platform 3 that can move up and down, and also includes a base 12, a scissor frame 13 and a power telescopic component 14. The two legs at the bottom front end of the scissor frame 13 are movably connected to the base 12, the two legs at the bottom rear end of the scissor frame 13 are both rotatably connected to the base 12, the two legs at the top front end of the scissor frame 13 are both movably connected to the lifting platform 3, and the two legs at the top rear end of the scissor frame 13 are both rotatably connected to the lifting platform 3. The power telescopic component 14 is rotatably installed on the base 12, and the telescopic end of the power telescopic component 14 is rotatably connected to the central axis of the scissor frame 13. The scissor frame 13 is composed of four inclined support rods, which are crossed and arranged opposite to each other, and the opposite support rods are parallel, and the two crossing positions are connected by the central axis. It can also be a scissor frame 13 of other structures, which belongs to the technology well known to those skilled in the art and will not be described in detail here; after folding, the thickness of this scissor frame 13 can be minimized, so that it can be suspended and hidden under the carrying trolley 2. The power telescopic component 14 is a hydraulic rod; the hydraulic rod has the characteristic of large load capacity and is suitable for heavier objects, such as a coring machine. Of course, the power telescopic component 14 can also be other telescopic components, such as an electric push rod, a screw push rod, etc.

[0026] The carrying trolley 2 includes a body 4 and moving wheels 5 installed on the body 4. The body 4 can be installed on the lifting platform 3 in a linearly movable manner. The body 4 and the lifting platform 3 are connected through rollers 7 and corresponding roller grooves 6. When the lifting platform 3 descends to the lowest point, the distance from the bottom side of the moving wheels 5 of the carrying trolley 2 to the top side of the lifting device 1 is greater than the distance from the bottom side of the lifting device 1 to the top side of the lifting device 1.

[0027] Specifically, roller grooves 6 are respectively provided on both sides of the lifting platform 3, and rollers 7 (such as Figure 1 and 2 As shown), the roller 7 rolls with the corresponding roller groove 6. The rolling cooperation of the roller 7 and the roller groove 6 has small friction, is lighter when moving, and has low manufacturing and maintenance costs; the two sides of the lifting platform 3 are connected with the two sides of the vehicle body 4 by rolling cooperation, the connection strength is high, and the stability of the vehicle body 4 when moving is high. As another way to install the vehicle body 4 on the lifting platform 3 so that it can move linearly, heavy-duty ball slides can be provided on the two outer sides of the top of the lifting platform 3, which are slidably connected to the vehicle body 4 through the heavy-duty ball slides; the two outer sides of the lifting platform 3 are connected with the two sides of the vehicle body 4 by heavy-duty ball slides, which can further improve the connection strength and the stability of the vehicle body when moving. The ball slides belong to the prior art and will not be described in detail here.

[0028] The vehicle body 4 is a U-shaped structure, the roller grooves 6 are arranged on the two opposite side end surfaces of the lifting platform 3, and the rollers 7 are arranged on the two opposite inner side end surfaces of the vehicle body 4 (such as Figure 1 As shown). The U-shape can save materials, effectively reduce costs, and make it easier to observe the situation of the lower lifting device 1. At the same time, it can be plugged into the two sides of the lifting platform 3 and movably connected to the two opposite side end surfaces of the lifting platform 3, which is more stable when moving. The body 4 is provided with a reinforcing rib 15, which is used to connect the two sides of the open end of the body 4. The reinforcing rib 15 can effectively improve the structural strength of the body 4, making it more load-bearing and less prone to deformation.

[0029] There are multiple moving wheels 5 on the vehicle body 4, and at least one of the multiple moving wheels 5 has a locking function. The moving wheels 5 with a locking function are mainly used to fix the coring machine to prevent the coring machine from being displaced as the vehicle body shakes after loading; in practice, there are four moving wheels 5, the two front wheels can be set as directional wheels, and the two rear wheels can be set as universal wheels with a braking function, which can play a role in all-round rotation and direction adjustment during the movement of the coring machine and can achieve the fixation of the coring machine.

[0030] The lifting platform 3 is in a U-shaped structure, and the vehicle body 4 is sleeved on the lifting platform 3 from top to bottom. The lifting platform 3 is set in a U-shaped structure, which can save more materials and facilitate the sleeve connection of the vehicle body 4, so that the vehicle body 4 and the lifting platform 3 have a higher connection strength.

[0031] The vehicle body 4 is fixedly connected to the lifting platform 3 through the locking assembly 8. When the vehicle body 4 is raised and the trolley 2 needs to be separated from the lifting platform 3 and moved in the vehicle body, the locking assembly 8 can be opened. When the vehicle body 4 is lowered and moved, in order to prevent the lifting device 1 from being separated from the trolley 2, the lifting platform 3 and the vehicle body 4 can be locked together through the locking assembly 8. The locking assembly 8 makes it easier for the trolley 2 and the lifting device 1 to move relative to each other and to lock the combination. The locking assembly 8 includes a U-shaped latch 9, a plug interface 10 provided on the lifting platform 3, and a plug hole 11 (such as a plug hole 12) provided on the vehicle body 4. Figure 4 As shown in FIG. 1 , the two legs of the U-shaped latch 9 can be respectively inserted into the insertion hole 11 and the insertion port 10. This lock assembly 8 has a simple structure, low cost and is easy to use. Of course, other lock assemblies 8 in the art can also be used to connect the lifting platform 3 and the vehicle body 4.

[0032] When in use, first control the lifting platform 3 to descend to the lowest level. At this time, the moving wheels 5 of the carrying trolley 2 support the ground, and the lifting device 1 is suspended below the carrying trolley 2. The lifting platform 3 is fixedly connected to the vehicle body 4 through the locking assembly 8. The coring machine is placed on the carrying trolley 2. Then the lifting device 1 and the coring machine can be moved and transported by the carrying trolley 2. When the coring machine is moved to the rear of the transport vehicle, it stops. Then the lifting device 1 is controlled to raise the lifting platform 3, so that the carrying trolley 2 and the coring machine are supported by the lifting device 1 together. When the bottom side of the moving wheels 5 of the carrying trolley 2 is flush with the surface of the carriage, the lifting stops. The locking assembly 8 is opened to release the lock, and the carrying trolley 2 is controlled to move from the lifting platform 3 to the carriage. At this time, the carrying trolley 2 is fixed and the lifting device 1 is controlled to descend to be folded up to above the plane of the carriage, and then moved to the bottom of the carrying trolley 2, and the carrying trolley 2 and the lifting platform 3 are fixedly connected by the locking assembly 8, and the coring machine and the lifting device 1 are moved to the designated placement position in the carriage by the carrying trolley 2, and the moving wheels 5 are locked and fixed, and the loading is completed; when unloading, the reverse operation is sufficient; after the coring machine is transported to a high or low place through this solution, there is no need to transfer it to other equipment. The coring machine can be loaded and unloaded by one person, and the transfer after loading and unloading can be completed, which saves time and effort, can effectively improve the handling efficiency, and reduce labor costs; this solution only takes the coring machine as an example, and other heavier items are also applicable.

[0033] The cross-height transport equipment is also provided with a rechargeable battery and a control device. The rechargeable battery is used to supply power, and the control device is used to control the movement of the hydraulic rod. The method of providing a rechargeable battery and using a control module to control the movement of the hydraulic rod belongs to the well-known technology in the field and will not be described in detail here. In this way, automatic control can be achieved by simply charging the battery, which well solves the problem that the loading and unloading of the coring machine in the road construction is time-consuming and labor-intensive and needs to be transferred to other tools for movement, saves labor, reduces the labor intensity of the coring personnel, and saves labor costs. In practice, four people were needed to move it in the past, but now only one person is needed, and each shift saves 3 laborers, saving about 3×150=450 yuan. The cost of this equipment can be recovered in basically 11 shifts, and the benefits are more obvious for projects with large engineering volume and frequent inspection frequency, and it can also be used for the cross-height transportation of other heavy objects.
