Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic lifting platforms, and particularly relates to a hydraulic lifting platform with a temperature control structure. Background Technique

[0002] A hydraulic lifting platform is a multi-functional lifting and loading / unloading mechanical equipment, mainly used for vertical transportation of goods or personnel in places such as buildings, warehouses, garages, logistics centers, etc.; it provides power through a hydraulic system to lift the platform from one height to another for easy loading and unloading of goods; there are various types of hydraulic lifting platforms, including four-wheel mobile type, two-wheel traction type, vehicle modified type, hand-pushed type, hand-cranked type, AC / DC dual-purpose type, and battery-powered vehicle-mounted type, etc., with lifting heights ranging from 1 meter to 30 meters.

[0003] Chinese Patent Grant Publication No. CN216038430U discloses a hydraulic lifting platform, which includes a bottom frame and a top frame arranged in parallel up and down. An elevating assembly is arranged between the bottom frame and the top frame. The elevating assembly includes a bottom cross beam fixed in the bottom frame, a top cross beam fixed in the top frame, a lower sliding beam slidably arranged in the bottom frame, an upper sliding beam slidably arranged in the top frame, two sets of scissor supports arranged opposite to each other front and back. One side of the scissor support is hinged to the top cross beam and the bottom cross beam at the upper and lower ends respectively, and the other side of the scissor support is hinged to the upper sliding beam and the lower sliding beam at the upper and lower ends respectively. A hydraulic cylinder is arranged between the bottom cross beam and the lower sliding beam. The solution provided by the embodiment of the utility model is that when painting operations are carried out, the hydraulic rod of the hydraulic cylinder extends, driving the top frame to descend to the designated working position. After the painting is completed, the hydraulic rod retracts to make the top frame rise flush with the ground; it is convenient for workers to enter the deep pit for painting operations.

[0004] Since the hydraulic lifting platform will be used in overheated or overcooled seasons or regions, it will cause the temperature of the hydraulic oil in the hydraulic oil tank to be too high or too low. Too high a temperature will cause the internal components of the machine to expand, which may cause equipment wear or the clearance of moving parts to be too small and jam, thus damaging the hydraulic system. Too low a temperature will increase the viscosity of the hydraulic oil, increase the pressure loss of the hydraulic system, and lead to reduced efficiency. When the viscosity is too high, the hydraulic system may not even work properly. For this reason, we propose a hydraulic lifting platform with a temperature control structure. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a hydraulic lifting platform with a temperature control structure, so as to solve the problems proposed in the above background technology. Since the hydraulic lifting platform will be used in overheated or overcooled seasons or regions, the hydraulic oil in the hydraulic oil tank will be too high or too low in temperature. Too high a temperature will cause the internal mechanical components to expand, which may cause equipment wear or the clearance of moving parts to be too small and jam, thus damaging the hydraulic system. Too low a temperature will increase the viscosity of the hydraulic oil, increase the pressure loss of the hydraulic system, and lead to reduced efficiency. When the viscosity is too high, the hydraulic system may not even work properly.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions: A hydraulic lifting platform with a temperature control structure, including the hydraulic lifting platform body.

An electric heating wire penetrates through the interior of the heat exchange tube. A heat insulation layer is installed on the inner wall of the hydraulic oil tank. A temperature sensor is installed above the inner wall of the heat insulation layer.

[0007] Preferably, the stirring rods are evenly distributed along the outer surface of the transmission rod, and the stirring rods enable the transmission rod and the stirring motor to rotate inside the hydraulic oil tank.

[0008] Preferably, the heat exchange tube penetrates through the interior of the hydraulic oil tank and is fixedly connected to the hydraulic oil tank.

[0019] Please refer to Figures 1-4 , a hydraulic lifting platform with a temperature control structure, including a hydraulic lifting platform body 1, a hydraulic oil tank 3 is installed at the front end of the hydraulic lifting platform body 1, a cooling fan 2 is installed on the left side of the hydraulic oil tank 3, a stirring motor 4 is installed above the hydraulic oil tank 3, a transmission rod 6 is installed at the output end of the stirring motor 4, and a stirring rod 8 is installed on the outer surface of the transmission rod 6; the stirring rods 8 are evenly distributed along the outer surface of the transmission rod 6, and the stirring rods 8 drive the transmission rod 6 and the stirring motor 4 to rotate inside the hydraulic oil tank 3; a heat exchange tube 7 is arranged inside the hydraulic oil tank 3; the heat exchange tube 7 penetrates through the inside of the hydraulic oil tank 3 and is fixedly connected to the hydraulic oil tank 3, and an electric heating wire 10 is arranged inside the heat exchange tube 7; the electric heating wire 10 penetrates through the inside of the heat exchange tube 7; the wind direction of the cooling fan 2 is parallel to the heat exchange tube 7, and a heat insulation layer 9 is installed on the inner wall of the hydraulic oil tank 3; the shape and size of the heat insulation layer 9 match the shape and size inside the hydraulic oil tank 3, and a temperature sensor 5 is installed above the inner wall of the heat insulation layer 9; by arranging a heating and cooling structure inside the hydraulic oil tank 3, when the hydraulic oil tank 3 is used in a place with overheating or overcooling, the hydraulic oil inside the hydraulic oil tank 3 can always be maintained within a suitable temperature range, avoiding damage or inability to work of the mechanical components of the hydraulic lifting platform due to too high or too low hydraulic oil temperature.

[0020] Working principle: When using the hydraulic lifting platform with a temperature control structure, first, the temperature sensor 5 monitors the temperature of the hydraulic oil inside the hydraulic oil tank 3. When it detects that the temperature of the hydraulic oil is too high, the temperature sensor 5 feeds back the information to the controller, and the controller controls the cooling fan 2 to work electrically. The cooling fan 2 drives the air to pass through the inside of the heat exchange tube 7, taking away the heat on the heat exchange tube 7. The heat in the hydraulic oil will be transferred to the heat exchange tube 7 again, thereby achieving the cooling of the hydraulic oil. At the same time, the controller controls the stirring motor 4 to work electrically to drive the stirring rod 8 on the transmission rod 6 to rotate, stirring the hydraulic oil to accelerate the heat transfer and improve the cooling efficiency. Then, when the temperature sensor 5 detects that the temperature of the hydraulic oil inside the hydraulic oil tank 3 is too low, the temperature sensor 5 feeds back the information to the controller, and the controller controls the electric heating wire 10 to work to heat the heat exchange tube 7. The heat exchange tube 7 then transfers the heat to the hydraulic oil. At the same time, the controller controls the stirring motor 4 to work electrically to drive the stirring rod 8 on the transmission rod 6 to rotate, stirring the hydraulic oil to make the hydraulic oil evenly heated. Secondly, the heat insulation layer 9 on the inner wall of the hydraulic oil tank 3 plays a role in heat insulation, reducing the influence of the external temperature on the inside of the hydraulic oil tank 3. Then, the oil pump works to pump the hydraulic oil inside the hydraulic oil tank 3 into the oil cylinder inside the hydraulic lifting platform body 1, controlling the hydraulic lifting platform body 1 to rise or fall. This is the working principle of the hydraulic lifting platform with a temperature control structure.
