Description

Technical Field

[0001] The utility model relates to the technical field of forklifts, in particular to a high-strength hydraulic forklift with an electronic scale. Background Art

[0002] Manual hydraulic forklifts are also known as manual lifting, loading and unloading and short-distance transportation vehicles. Since they do not generate sparks and electromagnetic fields, they are particularly suitable for loading and unloading of cars and loading and unloading of flammable, explosive and fire-prohibited items in workshops, warehouses, docks, stations, freight yards, etc. This product has the characteristics of balanced lifting, flexible rotation and easy operation. The door frame of the manual hydraulic stacker is made of heavy-duty column steel and is cold-bent, making the door frame stronger, safer, more flexible to move, and easy and labor-saving to operate.

[0003] The existing utility model patent application number is 201921375775.1, which relates to the field of hydraulic forklifts. It includes a support base, a steering wheel is fixedly installed below the support base, a steering mechanism is fixedly installed on the top of the support base, a control rod is fixedly connected to the top of the steering mechanism, a control handle is fixedly connected to the top of the control rod, a pneumatic switch is fixedly installed on one side of the top of the control rod, a fixed plate is fixedly installed on one side of the support base, an electronic scale is fixedly connected to the top of the fixed plate, a display screen is fixedly connected to the upper surface of the electronic scale, a charging port is provided in the middle of one side of the electronic scale, and a fixed cover is fixedly installed on the other side of the electronic scale. The utility model can effectively improve the flexibility of the forklift by arranging a steering mechanism on the support base and using the steering mechanism in conjunction with the control rod. The control rod can be easily operated through the control handle to control the steering wheel to change direction.

[0004] However, the hydraulic forklift of this patent is not strong enough. A general hydraulic forklift can only bear a weight of 3 tons. Moreover, the electronic scale display cannot be read in any direction, and the reading of the weighing value is not convenient. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a hydraulic forklift with high strength that can bear at least 5 tons of cargo, with forks that are not easily deformed and an electronic scale that can move and directly read the weight value, in order to address the deficiencies of the above-mentioned existing technologies.

[0006] To achieve the above-mentioned purpose, the following technical solution is adopted: a high-strength hydraulic forklift with an electronic scale, comprising a frame, the frame having at least two forks and a head located at the front end of the forks, the rear end of each fork being supported by a group of supporting wheel groups, the head being connected to a hydraulic lifting member, a handle and a steering wheel, the handle being rotated to cause the hydraulic lifting member to drive the fork to rise and fall, each fork being provided with a frame-type push rod, the frame push rod being hinged to a rocker arm at one end away from the supporting wheel group, the hydraulic lifting member realizing the lifting of the fork through the hinged rocker arm, the frame push rod being provided with at least two weight sensors distributed along the length direction, the bottom of each weight sensor being fixed with a reinforcement plate, thickened baffles being provided on both sides of the length direction of the fork, the two thickened baffles being connected to each other by a connecting plate at one end away from the supporting wheel group, the bottom of the thickened baffle being provided with a limiting groove for partially embedding the reinforcement plate in the thickened baffle, and the length of the reinforcement plate being the same as that of the connecting plate when the reinforcement plate is embedded in the limiting groove, and an electronic scale connected to the weight sensor via a signal line is also provided above the head.

[0007] By adopting the above technical solution, the structure of the fork is transformed from the original U-shape into a partially supporting hollow rectangle through the cooperation of the reinforcing plate and the limiting groove. The connection strength between the reinforcing plate and the limiting groove can also be increased by welding. Since the length of the reinforcing plate is the same as the connecting plate when the reinforcing plate is embedded in the limiting groove, the reinforcing plate is the same as the width and length of the fork after installation, and no part is exposed, resulting in reduced strength and unsightly appearance. Moreover, since the reinforcing plate is arranged at the bottom, it will not affect the shape of the outer surface of the product, and it can be more beautiful while increasing strength. The purpose of setting the signal line is to prevent the electronic scale from being lost. If the electronic scale and the weight sensor are wirelessly connected, the electronic scale is easy to be lost later. A number of protrusions for positioning and adjusting the direction can be provided on the top surface of the vehicle head and the bottom surface of the electronic scale. and grooves to prevent slipping during weighing. The frame-type push rod can also increase the contact area with the fork, thereby increasing the support strength. At the same time, a weight sensor can be placed inside it, and the weight sensor is positioned by a reinforcing plate. At the same time, the hydraulic lifting parts also increase the load-bearing weight, thereby increasing the overall strength of the fork after assembly. The signal line can be a spring line. Compared with ordinary signal lines, the spring line has an automatic return function and is not easy to tangle. It can also be convenient for it to be stored in the front of the vehicle. At the same time, the stretched length of the spring line is long enough. When the weighing weight is small, the electronic scale can move within the maximum stretched distance of the spring line and be held in the hand for operation. At the same time, the strength of the spring line is also high, and it is not easy to get off the line or break. The electronic scale and the front of the vehicle in this application can be connected in a fixed form, which is more stable.

[0008] A high-strength hydraulic forklift with an electronic scale can be further configured as follows: the thickness of the reinforcement plate, thickened baffle and connecting plate is 15-20 mm, and the load-bearing capacity of the fork and hydraulic lifting component is greater than or equal to 5 tons.

[0009] By adopting the above technical solution, the thickness of the thickened baffle, connecting plate and reinforcing plate is set to 15-20mm, preferably 16mm, so that the overall strength of the fork is increased. The existing hydraulic forklift can only bear a weight of 3 tons. At the same time, the hydraulic lifting parts also increase the lifting load-bearing capacity, and the electronic scale can also weigh a weight greater than or equal to 5 tons. The hydraulic forklift of this application can withstand a weight of at least 5 tons, thereby saving more transportation costs and improving transportation efficiency.

[0010] A high-strength hydraulic forklift with an electronic scale can be further configured as follows: the fork upper cover is provided with a fork cover, the fork cover is connected to a baffle arranged perpendicular to the fork cover at one end away from the supporting wheel group, and the fork cover is provided with four contacts that abut against a weight sensor on the side facing the fork.

[0011] By adopting the above technical solution, the fork cover can effectively protect the fork and further increase the overall strength of the fork. The baffle can support the cargo to prevent the cargo from directly colliding with the front of the vehicle. When the cargo is placed on the fork cover, the weight of the cargo can be sensed in all directions through four contacts, making the measurement more accurate.

[0012] A high-strength hydraulic forklift with an electronic scale can be further configured as follows: the supporting wheel group includes a wheel frame and a double chain plate, the upper end of the wheel frame is hinged to the fork, the double chain plate is connected to the lower end of the wheel frame, and two wheels are arranged in the double chain plate.

[0013] By adopting the above technical solution, the double-wheel setting makes the support stronger, and at the same time improves the smoothness of the sliding of the hydraulic forklift. The wheel frame can also be rotated and lifted as the fork is lifted, making the lifting process smoother.

[0014] A high-strength hydraulic forklift with an electronic scale can be further configured as follows: an electronic scale connected to a weight sensor via a signal line is provided above the vehicle head; the electronic scale can rotate or move within the vehicle head through the range of the signal line; the signal line is a low-lying spring line provided at the bottom of the electronic scale; a through hole is provided on the vehicle head; the signal line is hidden in the vehicle head through the through hole; the electronic scale can rotate on the vehicle head or the electronic scale can be moved within the vehicle head by pulling out the signal line from the through hole.

[0015] With this technical solution, the signal cable can be coiled and placed inside the vehicle's hood when not in use. When extended, the user can simply hold the electronic scale in their hand and operate it, providing more versatile operation options. The signal cable also prevents the electronic scale from leaving its range of motion, making it less likely to be lost and providing an anti-theft feature. Compared to ordinary signal cables, the spring cable has an automatic return function, making it less prone to tangling and conveniently stored inside the vehicle's hood. The extended length of the spring cable also allows the electronic scale to be moved within its extended range and operated while held in the hand. The spring cable is also strong, making it less likely to become disconnected or break. Furthermore, the low-profile spring cable can be hidden inside the vehicle's hood through a through hole when not in use, and then extended for ease of use.
