Description

Technical Field

[0001] The invention relates to the technical field of transport hoppers, and in particular to a movable electric-assisted hopper and a use method thereof. Background Art

[0002] During the construction of housing projects, due to site limitations, construction safety regulations and other reasons, the operating radius of large lifting equipment such as tower cranes cannot cover the entire construction site, which will result in some materials being unable to be transported vertically. Therefore, workers generally use tower cranes to pull or carts to transport materials to the lifting point. The use of tower cranes to pull will cause the wire rope to deviate from the vertical direction, and its force is greater than the gravity of the lifting object, which is easy to cause overload; secondly, safety accidents such as tower crane overturning may occur, causing casualties. The method of using a cart to transport materials to the lifting point and then transporting them to the hopper will result in secondary transportation, reducing construction efficiency. Although the use of hydraulic manual forklifts to transport materials horizontally can partially solve this problem, due to the various forms of material components on the construction site, the center of gravity is high during the material loading process, and the complex situation of the civil engineering construction work surface makes it very easy for the material stacking to collapse during the horizontal transportation process, which may cause property losses at the least and casualties at the worst. Therefore, a hopper that is easy to transport and can ensure the safety of lifting is now needed to solve the difficulties in vertical transportation of materials outside the blind area of ​​the tower crane. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a movable electric power-assisted hopper and a method for using the same, which has the advantages of convenient transportation, improved construction efficiency, low energy consumption, safe use, and meeting the requirements of standardized construction sites.

[0004] To achieve this technical purpose, the present invention adopts the following scheme: a movable electric power-assisted hopper, including a hopper, a lifting ring, an electrical drive system and a traveling wheel. The traveling wheel is connected to the bottom of the hopper, and the electrical drive system is installed at the bottom of the hopper. The electrical drive system drives the traveling wheel to rotate and move; a lifting ring is fixed on the upper part of the hopper for connecting the tower crane hanging rope.

[0005] Compared with the prior art, the beneficial effects of the present invention are: the hopper has the functions of both lifting and plane transportation, is easy to operate, and effectively solves the problems of high safety risks, slow speed, and failure to meet the requirements of safe and civilized construction in the vertical transportation of materials outside the blind area of ​​the tower crane during the construction of building projects.

[0006] Furthermore, a steering system is provided at the bottom of the hopper to change the traveling direction of the traveling wheels.

[0007] Furthermore, the steering system includes a fixed shaft, an eccentric disk, a driven steering shaft, an active steering shaft, a semicircular gear and an operating lever. The lower end of the operating lever is fixedly connected to the semicircular gear. The active steering shaft is provided with a transverse rack, which meshes with the semicircular gear. Both ends of the active steering shaft are respectively connected to a driven steering shaft, which is connected to the fixed shaft at its midpoint. The fixed shaft is arranged on the bottom of the hopper so that the driven steering shaft rotates around the fixed shaft. The other end of the driven steering shaft is connected to the eccentric position of the eccentric disk. A walking wheel is connected to the bottom of the eccentric disk. The rotation of the eccentric disk drives the walking wheel to rotate, thereby changing the walking direction. Furthermore, the electric drive system includes an operating button, a battery pack and a drive mechanism. The operating button controls the start and stop of the drive mechanism, the drive mechanism drives the running wheels to rotate, and the battery pack provides electrical energy for the drive mechanism.

[0008] Furthermore, it also includes a charging socket for connecting a charging cable to store electrical energy for the battery pack.

[0009] A method for using a movable electric power-assisted hopper. The movable electric power-assisted hopper has a structure as described above, and the steps for using the movable electric power-assisted hopper are as follows: When the hopper is full of materials, the forward or backward movement of the hopper is controlled by the operating button, and the forward direction of the hopper is changed by turning the operating lever to complete the ground or foundation surface transportation of materials; When the hopper moves to the unloading platform, connect the lifting ring of the hopper with the hanging rope, and use the tower crane to lift the hopper to complete the vertical transportation of the material.

[0010] Furthermore, when transporting materials, the height of the materials in the hopper cannot exceed the height of the hopper wall.

[0011] Compared with the existing tower crane oblique pull or horizontal transport secondary transport, the present invention has the following characteristics: ① Convenient transportation and improved construction efficiency: The hopper is equipped with an electric drive system, which can achieve vertical transportation after one-time transportation to the lifting point. Compared with the horizontal transportation of a trolley, the material still needs to be moved into the hopper after the second reversal before vertical transportation, which greatly improves the construction efficiency and saves labor costs.

[0012] ②Safety in use: The hopper is equipped with four lifting rings to meet the lifting requirements of large tower crane lifting equipment. At the same time, it avoids the illegal operation of workers using the tower crane to pull the slant because they are not within the operating range of the tower crane, thus eliminating the existing safety hazards.

[0013] ③Easy to operate and low energy consumption: The moving direction of the hopper can be controlled by the operating lever; the two active walking wheels are equipped with 5.5-inch hub motors, and the moving speed is low during the working process, so the energy consumption is low and the energy-saving effect is good; the four wheels are divided into two groups, and the outer rings of the wheels are covered with soft rubber, which reduces the vibration generated during the horizontal transportation of the hopper and avoids damage to the completed ground pavement.

[0016] like Figures 1 to 4 As shown, the present invention provides a movable electric power-assisted hopper, including a hopper, a lifting ring 3, an electrical drive system and a travel wheel. The hopper is an open hopper, and the lifting rings 3 are welded on the upper edges of the four sides of the hopper respectively, which are used to connect the hanging rope of the tower crane. Travel wheels are installed on the lower side of the hopper bottom plate, wherein the active travel wheel 1 is installed at the front end, and the driven travel wheel 2 is installed at the rear end. An electrical room is provided at the bottom of the hopper, and an electrical drive system is installed in the electrical room. The electrical drive system is connected to the active travel wheel 1 to drive the active travel wheel 1 to rotate and travel. The electrical drive system includes an operation button 6, a battery pack 12 and a drive mechanism. The operation button 6 is connected to the drive mechanism in communication, and the start and stop of the drive mechanism are controlled by the operation button 6. The battery pack 12 provides electrical energy to the drive mechanism, and the drive mechanism drives the active travel wheel 1 to rotate. The drive mechanism is any drive structure in the prior art that can drive the trolley roller forward or backward, and can be a connection form such as a motor, a gear, and a rotating shaft, which will not be described in detail here. Preferably, the active travel wheel 1 is a 5.5-inch hub motor, and the outer ring of the wheel is covered with soft rubber, which can reduce the vibration of the hopper and avoid damaging the newly paved ground.

[0017] The bottom of the hopper is also provided with a steering system for changing the direction of travel of the running wheel. The steering system includes a fixed shaft 10, an eccentric disk 11, a driven steering shaft 9, an active steering shaft 8, a semicircular gear 7 and an operating rod 4. The operating rod 4 is placed vertically, and the middle part of the operating rod 4 is hinged to the side wall of the hopper, so that the upper end of the handheld operating rod 4 can be rotated and the lower end of the operating rod 4 can be rotated in the opposite direction. The lower end of the operating rod 4 is fixedly connected to the plane end of the semicircular gear 7. A transverse rack is provided in the middle part of the active steering shaft 8, and the semicircular gear 7 is meshed with the transverse rack. The two ends of the active steering shaft 8 are respectively connected to a driven steering shaft 9 through a rotating shaft. The middle part of each driven steering shaft 9 is connected to a fixed shaft 10, which is vertically connected to the bottom plate of the hopper and can rotate by itself, that is, the driven steering shaft 9 rotates around the fixed shaft 10, and the other end of the driven steering shaft 9 is connected to the eccentric position of the eccentric disk 11, and the lower side of the eccentric disk 11 is connected to the active running wheel 1.

[0018] The rotation of the upper end of the operating lever 4 causes the semicircular gear 7 at the lower end of the operating lever 4 to rotate, driving the transverse rack (active steering) to swing left or right, and further driving the driven steering shaft 9 to rotate around the fixed shaft 10, thereby changing the position of the eccentric disk 11 and changing the traveling direction of the active walking wheel 1.

[0019] Preferably, the operating button is arranged at the upper end of the operating rod for easy operation.

[0020] In some preferred embodiments, the battery pack 12 uses a rechargeable battery, and the hopper is also provided with a charging socket 5 for connecting a charging line to store electrical energy for the battery pack 12 .

[0021] How to use: When the hopper is full of materials, the forward / reverse movement of the hopper is controlled by the operating button 6 on the operating lever 4, and the forward direction is changed by rotating the operating lever 4 to complete the horizontal transportation of materials. When the hopper is moved to the unloading platform, the steel wire rope on the hook and the lifting rings 3 on the four corners of the hopper are used to lift the hopper to complete the vertical transportation of materials. When the work is finished for the day, move the hopper to the designated location on site and charge it through the charging port below.

[0022] A rechargeable battery and a steering system are installed in the hopper. The bogie system is connected by a transverse rack and a semicircular gear under the handle. When the handle moves left or right, the semicircular gear drives the rack to move laterally, and then drives the active walking wheel to change direction through the connecting rod rotating around the fixed axis.

[0023] Finally, it should be noted that the above are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention.
