Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an environmentally friendly semi-automatic curbstone installation trolley and its construction method. Background Technology

[0002] The curb stones on both sides of the road are characterized by long linear mileage, large weight of a single curb stone, large amount of manual labor required for installation, and slow installation speed.

[0003] The current mainstream method for installing curb stones is to use simple transport vehicles to transport the curb stones one by one. After they are transported to the appropriate location, the curb stones are manually adjusted in position before installation. This method is relatively slow and labor-intensive. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, an environmentally friendly semi-automatic curbstone installation trolley and its construction method are provided to solve the problems of slow installation speed and labor-intensive operation of existing curbstone installation methods.

[0005] To achieve the above objectives, an environmentally friendly semi-automatic curbstone installation trolley is provided, comprising:

[0006] The vehicle frame is equipped with electric rollers at its front and rear ends, a material platform for stacking curb stones to be paved is installed at the front end of the vehicle frame, and a scraper with adjustable height for smoothing dry mortar on the road surface to form a mortar layer is installed on one side of the vehicle frame.

[0007] A conveyor belt is installed at the rear end of the vehicle frame, and the conveyor belt has an input end and an output end;

[0008] A cantilever crane used for lifting the curb stones to be paved and transporting them to the input end is rotatably mounted on the front end of the vehicle frame;

[0009] An inclined guide ramp is installed on one side of the vehicle frame. The output end is aligned with the upper end of the guide ramp. A baffle is formed on the side of the guide ramp away from the vehicle frame. The baffle, the guide ramp, and the vehicle frame enclose an inclined slide for the curb stone to be paved to slide.

[0010] A sensor is mounted on the vehicle frame and aligned with the lower end of the inclined slide.

[0011] The controller is connected to the electric roller, the conveyor belt, and the sensor. After the curbstone to be paved is fed into the upper end of the inclined slide at the output end of the conveyor belt, the curbstone slides onto the mortar layer under its own gravity. When the curbstone passes through the inclined slide, the sensor generates a forward movement signal. The controller receives the forward movement signal and starts the electric roller, while simultaneously turning off the conveyor belt. When the curbstone leaves the inclined slide, the sensor generates a stop signal. The controller receives the stop signal and turns off the electric roller, while simultaneously turning on the conveyor belt.

[0012] Furthermore, the hook of the cantilever crane is equipped with a clamp for holding the curbstone to be paved.

[0013] Furthermore, the clamp is a scissor clamp.

[0014] Furthermore, a limiting plate is formed on the side of the conveyor belt facing the rear end of the vehicle frame.

[0015] Furthermore, the sensor is a photoelectric sensor.

[0016] This invention provides a construction method for an environmentally friendly semi-automatic curbstone installation trolley, comprising the following steps:

[0017] a. Lay dry-mixed mortar on the side of the road surface;

[0018] b. Adjust the height of the scraper on one side of the frame so that the height of the scraper is adapted to the top elevation of the mortar layer;

[0019] c. Move the vehicle frame onto the road surface so that the scraper is positioned above the dry-mixed mortar spread on the side of the road surface, and stack multiple curb stones to be paved on the material loading platform of the machine frame.

[0020] d. The controller starts the conveyor belt;

[0021] e. A cantilever crane lifts a curbstone to be paved and transfers it to the input end of the conveyor belt;

[0022] f. The conveyor belt feeds the curbstone to be paved into the upper end of the inclined chute;

[0023] g. The curbstone to be paved slides onto the mortar layer via the inclined slide under its own weight. When the curbstone to be paved passes through the inclined slide, the sensor generates a forward movement signal.

[0024] h. The controller receives the forward movement signal and starts the electric roller, while simultaneously shutting down the conveyor belt;

[0025] i. During the forward movement of the vehicle frame, the curb to be paved gradually detaches from the inclined slide. When the curb to be paved detaches from the inclined slide, the sensor generates a stop signal.

[0026] j. The controller receives the stop signal and shuts off the electric roller, while simultaneously starting the conveyor belt;

[0027] k. Repeat steps e to j to install the curb stones to be paved one by one.

[0028] The beneficial effects of this invention are that the environmentally friendly semi-automatic curbstone installation trolley of this invention can conveniently and quickly achieve high-precision installation of curbstones. It has diversified functions such as transportation, conveying, leveling, and semi-automatic installation, solving the curbstone installation problem in one stop and improving the installation efficiency and quality of curbstones.

[0035] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Reference Figures 1 to 5As shown, the present invention provides an environmentally friendly semi-automatic curbstone installation trolley, comprising: a frame 1, a conveyor belt 2, a cantilever crane 3, a guide ramp 4, a sensor 5, and a controller 8.

[0038] Electric rollers 11 are installed at both the front and rear ends of the frame 1. A material loading platform for stacking curb stones 6 to be paved is installed at the front end of the frame 1. A scraper 12 with adjustable height is installed on one side of the frame 1 for smoothing dry-mixed mortar on the road surface to form a mortar layer 7.

[0039] Conveyor belt 2 is installed at the rear end of the frame 1. Conveyor belt 2 has an input end and an output end.

[0040] A cantilever crane 3 is used to lift the curb stones 6 to be laid and transport them to the input end. It is rotatably mounted on the front end of the frame 1.

[0041] An inclined guide ramp 4 is installed on one side of the frame 1. The output end is aligned with the upper end of the guide ramp 4. A baffle 41 is formed on the side of the guide ramp 4 away from the frame 1. The baffle 41, the guide ramp 4, and the frame 1 enclose an inclined slide for the curb stone 6 to be paved to slide on.

[0042] Sensor 5 is mounted on the frame 1 and aligned with the lower end of the inclined slide.

[0043] The controller 8 is connected to the electric roller 11, the conveyor belt 2, and the sensor 5.

[0044] After the curbstone 6 to be paved is fed into the upper end of the inclined slide at the output end of the conveyor belt 2, the curbstone 6 to be paved slides onto the mortar layer 7 under its own gravity.

[0045] When the curbstone 6 to be paved passes through the inclined slide, the sensor 5 generates a forward movement signal, the controller 8 obtains the forward movement signal and starts the electric roller 11, while simultaneously shutting off the conveyor belt 2.

[0046] When the curbstone 6 to be paved is removed from the inclined slide, the sensor 5 generates a stop signal, the controller 8 receives the stop signal and shuts off the electric roller 11, and at the same time starts the conveyor belt 2.

[0047] The environmentally friendly semi-automatic curbstone installation trolley of this invention can conveniently and quickly achieve high-precision installation of curbstones. It has diversified functions such as transportation, conveying, leveling, and semi-automatic installation, providing a one-stop solution for curbstone installation problems.

[0048] The frame 1 has an overall length of 2.5m and a width of 2.0m. The frame is composed of Q235 I-beams, square steel, and patterned steel plates.

[0049] Three electric rollers are installed at each end of the frame. The diameter of each electric roller is no greater than 30cm. Each roller has a load-bearing capacity of no less than 1000kg. The front wheels use a steering gear + steering transmission mechanism (utilizing the steering principle of automobile front wheels), while the rear wheels use a high-power electric motor with a rated power of no less than 3KW + a right-angle steering gear.

[0050] A height-adjustable scraper is installed on the side of the frame near the curb mounting location. (See also...) Figure 3 and Figure 4 As shown, a bracket is connected to one side of the frame. The bracket is composed of square steel tubes. The square steel tubes are vertically arranged, and vertically arranged strip holes are opened on the square steel tubes. An ear plate is formed on one side of the scraper. Bolts are connected to the ear plates. The bolts slide in the strip holes. A locking element is screwed onto the end of the bolt away from the scraper. The locking element has a threaded hole. The locking element is screwed onto one end of the bolt to press against the steel frame and thus lock the scraper to fix the height of the scraper.

[0051] The side of the chassis furthest from the curb installation location is reinforced to form a loading platform. Specifically, the loading platform uses dense square steel as a frame to transfer forces to the entire chassis structural beams, and the uninstalled curb stones are stacked on top of the loading platform.

[0052] The transmission distance of the conveyor belt shall not exceed 1.2m, and the width of the conveyor belt shall not be less than 1.0m (it can be adjusted according to the length of the curbstone to meet the installation length of the curbstone).

[0053] The rated power of the drive motor of the conveyor belt is not less than 1kw. A differential is installed at one end of the drive motor to reduce the belt transmission speed and control the curb stone transmission speed.

[0054] In a preferred embodiment, a limiting plate is formed on the side of the conveyor belt 2 facing the rear end of the vehicle frame 1. Specifically, a limiting plate for aligning the curbstone is integrally welded to one side of the conveyor belt. The limiting plate has a thickness of not less than 0.5 cm and a height of not less than 10 cm, used to control the posture of the curbstone as it is hoisted onto the conveyor belt, ensuring accurate installation of the curbstone. An adjustable limiting ramp is provided on the other side of the conveyor belt to assist in adjusting the posture of the curbstone before it falls.

[0055] A set of support rollers is installed every 5cm at the bottom of the conveyor belt, and the support rollers bear the weight of the curb stones on the belt.

[0056] The conveyor belt is equipped with a curbstone limiter at the end of the belt. The end plate is adjusted according to the width and length of the curbstone. The width of the limit steel plate is not less than 0.5cm, and the height of the bottom of the steel plate is not more than 10cm from the bottom of the curbstone installation.

[0057] In this embodiment, the hook 31 of the cantilever crane 3 is equipped with a clamp for holding the curb stone 6 to be paved.

[0058] In a preferred embodiment, the clamp is a scissor clamp 32. Specifically, a clamp is installed on the hook 31 at the front end of the cantilever crane. The clamp is a scissor-type structure. The scissor clamp is cut and machined from a 1cm thick steel plate. The scissor clamp includes two Z-shaped steel plates. The middle parts of the two Z-shaped steel plates are hinged together by a hinge shaft. A chain is connected between the upper ends of the Z-shaped steel plates, and a ring is connected to the middle of the chain. When the ring is lifted, the scissor-type structure can automatically clamp.

[0059] For further details, please refer to [link / reference]. Figure 5 As shown, the lower ends of the two Z-shaped steel plates extend towards each other to form supporting flanges. Construction workers clamp the lower ends of the two Z-shaped steel plates to the curbstone and place the supporting flanges at the bottom of the curbstone. Then, after the central ring of the chain is attached to the hook, as the sling of the cantilever crane contracts, the hook lifts the chain, thereby reducing the distance between the upper ends of the two Z-shaped steel plates, and the lower ends of the two Z-shaped steel plates self-clamp the curbstone.

[0060] When the curbstone held by the Z-shaped steel plates is placed on the conveyor belt, the tension between the upper ends of the two Z-shaped steel plates disappears, making it easy for the lower ends of the two Z-shaped steel plates to open and release the curbstone.

[0061] The boom (horizontal member) of the cantilever crane is made of steel pipe with a wall thickness of not less than 2.0mm, and the end for lifting curb stones uses a hook with a load capacity of not less than 150kg.

[0062] The support rod (vertical member) of the cantilever crane is a hollow cylinder with a wall thickness of not less than 3.0mm, and a ring welded to the top for passing over the pry bar. The height of the support rod is not less than 1.0m.

[0063] The bottom of the cantilever crane's support rod is welded to a slewing bearing that can rotate on the base plate, used for adjusting the position of the curb by rotating the lever.

[0064] Both the drive motor and the transmission motor are powered by batteries. The battery pack is located at the front of the frame, and the battery specifications are no less than 48V 120A, which is matched with the drive motor and the transmission motor.

[0065] The rear wheels use a high-power electric motor with a rated power of not less than 3KW.

[0066] In a preferred embodiment, sensor 5 is a photoelectric sensor. Specifically, a distance-type photoelectric sensor is installed below the output end of the conveyor belt. It is in one state before the curb falls. When the curb falls, the distance of the reflected light becomes shorter, and the photoelectric sensor changes to another state, so that the controller can control the movement of the vehicle frame and the start and stop of the conveyor belt.

[0067] The chassis is equipped with a control console, on which the controller is mounted. The control console has a total of three switches, used to control the overall current input, the power motor current input, and the drive motor current input.

[0068] A delay regulator is installed at the front end of the power motor switch to adjust the forward distance of the chassis caused by the inertia of the vehicle during movement.

[0069] This invention provides a construction method for an environmentally friendly semi-automatic curbstone installation trolley, comprising the following steps:

[0070] a. Lay dry-mixed mortar on the side of the road surface.

[0071] b. Adjust the height of the scraper 12 on one side of the frame 1 so that the height of the scraper 12 is adapted to the top elevation of the mortar layer 7.

[0072] c. Move the frame 1 to the road surface so that the scraper 12 is positioned above the dry-mixed mortar spread on the side of the road surface, and stack multiple curb stones 6 to be paved on the material loading platform of the frame.

[0073] d. Controller 8 starts conveyor belt 2.

[0074] e. The cantilever crane 3 lifts a curb stone 6 to be paved and transfers it to the input end of the conveyor belt 2.

[0075] f. Conveyor belt 2 feeds the curb stones 6 to be paved into the upper end of the inclined slide.

[0076] g. The curbstone 6 to be paved slides onto the mortar layer 7 via an inclined slide under its own gravity. When the curbstone 6 passes through the inclined slide, the sensor 5 generates a forward movement signal.

[0077] h. Controller 8 receives the forward movement signal and starts the electric roller 11, while simultaneously shutting down the conveyor belt 2.

[0078] i. As the vehicle frame 1 moves forward, a curbstone 6 to be paved gradually detaches from the inclined slide. When the curbstone 6 detaches from the inclined slide, the sensor 5 generates a stop signal.

[0079] j. Controller 8 receives a stop signal and shuts off the electric roller 11, while simultaneously starting the conveyor belt 2.

[0080] k. Repeat steps e to j to install the curb stones to be paved one by one.

[0081] Before using this environmentally friendly semi-automatic curbstone installation trolley, the base layer (i.e., mortar layer) of the curbstone must be completed, and the curbstone is loaded onto the trolley's loading platform. The trolley is driven to the front of the desired curbstone installation location, and workers manually lift the curbstone onto the conveyor belt using a cantilever crane. Because a scraper is located at the front of the trolley, it smooths the dry-mixed mortar and adjusts the flatness of the curbstone base layer as the trolley moves forward, ensuring the bottom elevation matches the base layer elevation. The trolley is then started, and as it moves forward, the base layer elevation adjustment device moves accordingly, removing any material that exceeds the base layer elevation.

[0082] After the trolley has traveled a certain distance, the controller turns on all switches, activating the photoelectric sensors. The photoelectric sensors detect that the location is unobstructed and send a forward signal to the controller. The controller then stops the power motor (connected to the electric rollers) and starts the conveyor belt, which then begins operation.

[0083] The conveyor belt starts transporting the curbstones, which fall to designated positions. Upon landing, the curbstones block the photoelectric sensors. The blocked sensors generate a forward movement signal, which is sent to the controller. The controller then activates the power motor, shutting off the conveyor belt and stopping it from operating.

[0084] After the power motor starts working, the photoelectric sensor moves along with the trolley. After moving to the front of the previously placed curbstone, it detects that there is no obstruction and generates a stop signal, which is then sent to the controller. The controller receives the stop signal and repeats the previous steps. During the cyclical installation process, the cantilever crane needs to be operated manually to continuously lift the curbstone onto the conveyor belt, ensuring that the conveyor belt has a sufficient supply of curbstones.

[0085] In the early stages of curbstone installation, it is necessary to adjust the delay regulator on the controller to adjust the trolley travel distance after power failure, ensuring that the gap width between curbstones meets the design requirements.

[0086] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
