Description

Technical Field

[0001] This utility model relates to the field of vehicle support and stability technology, and in particular to a support device for preventing the mobile energy storage heating vehicle from falling. Background Technology

[0002] The workflow of a mobile energy storage heating vehicle can be simply summarized as "heat charging - heat storage - transportation - heat release". At the heat source (such as a power plant, waste incineration plant, or factory with industrial waste heat), the vehicle uses pipelines to charge waste or surplus heat energy (in the form of steam or hot water) into its storage tank. The tank is filled with special high-performance heat storage materials (such as phase change materials or specially designed heat storage particles). These materials store heat energy during the heating process. The tractor unit then transports the fully charged tank to the user who needs the heat energy, breaking the limitations of fixed pipelines. Upon arrival at the user's site, the stored heat energy is released to the heat-using equipment through pipeline connections, meeting their production, heating, or domestic hot water needs. The mobile energy storage heating vehicle's outriggers support the vehicle body and ensure the stability of the equipment during the charging and heat release processes. The average daily turnover rate is more than 3 times, and can reach up to 8 times (charging + heat release counts as 1 time), meaning the outriggers need to complete 6-16 lifting and lowering operations daily (lifting + retraction counts as 1 time).

[0003] Currently, mobile energy storage heating vehicles commonly use hydraulic outriggers as their support structure. However, in practical applications, this device has significant defects that seriously affect the stability and safety of the equipment. The most prominent problem is internal leakage in the hydraulic cylinders of the outriggers. Because the sealing of the hydraulic system is difficult to maintain ideally at all times, slow leakage inevitably occurs inside the cylinders, causing the outriggers to gradually descend during prolonged support operations. This settlement not only reduces the overall stability of the equipment but may also interfere with the normal operation of the heating system and even pose safety hazards. Furthermore, hydraulic outriggers have poor reliability, requiring frequent maintenance and adjustments, increasing operating costs and complexity. Therefore, the application of hydraulic outriggers in current mobile energy storage heating vehicles remains significantly limited, and technological improvements or alternative solutions are urgently needed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing heating vehicle support devices, where the hydraulic system's sealing is difficult to maintain at an ideal state, inevitably leading to slow leakage inside the cylinders and causing the outriggers to gradually descend during prolonged support operations. This settlement not only reduces the overall stability of the equipment but may also interfere with the normal operation of the heating system and even pose safety hazards. Furthermore, hydraulic outriggers have poor reliability, requiring frequent maintenance and adjustments, increasing operating costs and complexity. This invention provides a support device to prevent the outriggers from descending in mobile energy storage heating vehicles.

[0005] The purpose of this utility model is achieved through the following technical solution: a mobile energy storage heating vehicle anti-fall support device, including a base, a hydraulic cylinder installed on the base, a heating vehicle support leg installed on the telescopic end of the hydraulic cylinder through a piston rod, the heating vehicle support leg being used to support the heating vehicle, a locking block installed in the middle of the piston rod, and two sets of movable support blocks installed on the base.

[0006] The support block is in the shape of a right trapezoid. Setting the support block in the shape of a right trapezoid can make the bottom of the support block stronger and improve the stability of the support block when supporting the locking block. In addition, the two sets of support blocks are symmetrical about the piston rod, and the top of the support block is used to support the bottom of the locking block.

[0007] A sliding groove is provided on the base, and a motor is installed on one side of the base. The power output end of the motor extends into the sliding groove and is equipped with a lead screw. The lead screw has two sets of threads with opposite directions, and nuts are installed on both sets of threads. The two sides of the nuts are slidably connected to the inner wall of the sliding groove, and the two sets of nuts are respectively connected to the bottom of two sets of support blocks. By setting a piston rod on the hydraulic cylinder, the heating vehicle outriggers are pushed up to the heating support height. The motor is started, which drives the lead screw to rotate. Under the action of the two sets of opposite threads on the lead screw, the two sets of nuts move towards each other, so that the top of the support block contacts the bottom of the locking block. This provides support for the piston rod and the heating vehicle outriggers when the piston rod descends due to internal leakage in the hydraulic cylinder. This provides stable protection for the heating vehicle on the outriggers, prevents equipment failure caused by the heating vehicle descending with the piston rod, and ensures the efficient, stable, and safe operation of the heating vehicle.

[0008] A further technical solution is that the bottom surface of the support block is slidably connected to the upper part of the base, and the width of the bottom surface of the support block is greater than the width of the sliding groove. Setting the bottom surface width of the support block to be greater than the width of the sliding groove can enable the support block to move stably on the base, while the base can provide sufficient support force to the support block.

[0009] A further technical solution involves installing a pressure sensor corresponding to the locking block on the upper surface of the support block. The pressure sensor is connected to an external control terminal. By setting the pressure sensor, the pressure between the locking block and the support block can be monitored. When an internal leakage fault occurs in the hydraulic cylinder, the pressure sensor can detect a sharp increase in pressure between the locking block and the support block. External personnel can determine whether the hydraulic cylinder has malfunctioned by checking the pressure value monitored by the pressure sensor displayed on the external control terminal, and repair the equipment in a timely manner to avoid greater losses caused by misoperation.

[0010] A further technical solution is to install reinforcing ribs on the upper part of the locking block, which are connected to the piston rod. By setting reinforcing ribs, the strength between the locking block and the piston rod can be improved, thereby improving the stability of the device.

[0011] A further technical solution is that two sets of protective plates are installed on the upper part of the base. The two sets of protective plates are located on both sides of the support block, and the inner side of the protective plates is slidably connected to the support block. The hydraulic cylinder is located between the two sets of protective plates and the two sets of support blocks. By setting two sets of protective plates, the two sides of the support block can be supported, thereby preventing the support block from deforming when supporting the heating vehicle and improving the overall strength of the equipment.

[0012] This utility model has the following advantages: By setting a piston rod on the hydraulic cylinder to push the outriggers of the heating vehicle upward, the heating vehicle reaches the height of the heating support. The starting motor drives the lead screw to rotate, and the two sets of nuts move towards each other under the action of two sets of opposite threads on the lead screw, so that the top of the support block contacts the bottom of the locking block. In this way, when the piston rod descends due to internal leakage in the hydraulic cylinder, it supports the piston rod and the outriggers of the heating vehicle, thereby providing stable protection for the heating vehicle on the outriggers and preventing equipment failure caused by the heating vehicle descending with the piston rod, ensuring the efficient, stable and safe operation of the heating vehicle.

[0023] like Figures 1-3 As shown, a mobile energy storage heating vehicle anti-fall support device includes a base 1, a hydraulic cylinder 2 installed on the base 1, a heating vehicle support leg 4 installed on the telescopic end of the hydraulic cylinder 2 through a piston rod 3, the heating vehicle support leg 4 is used to support the heating vehicle, a locking block 5 is installed in the middle of the piston rod 3, and two sets of movable support blocks 7 are installed on the base 1.

[0024] The support block 7 is a right trapezoid. Setting the support block 7 as a right trapezoid can make the bottom of the support block 7 stronger and improve the stability of the support block 7 when supporting the locking block 5. The two sets of support blocks 7 are symmetrical about the piston rod 3. The top of the support block 7 is used to support the bottom of the locking block 5.

[0025] A sliding groove 8 is provided on the base 1. A motor 6 is installed on one side of the base 1. The power output end of the motor 6 extends into the sliding groove 8 and is fitted with a lead screw 12. The lead screw 12 has two sets of threads with opposite directions of rotation. Nuts 13 are installed on both sets of threads. The two sides of the nuts 13 are slidably connected to the inner sidewall of the sliding groove 8. The two sets of nuts 13 are respectively connected to the bottom of the two sets of support blocks 7. By setting the piston rod 3 on the hydraulic cylinder 2 to push the heating vehicle support leg 4 to rise, the heating vehicle reaches the height of the heating support. The motor 6 is started to drive the lead screw 12 to rotate. Under the action of the two sets of threads with opposite directions of rotation on the lead screw 12, the two sets of nuts 13 move towards each other, so that the top of the support block 7 contacts the bottom of the locking block 5. In this way, when the piston rod 3 of the hydraulic cylinder 2 falls due to internal leakage, it supports the piston rod 3 and the heating vehicle support leg 4, thereby providing stable protection for the heating vehicle on the heating vehicle support leg 4, avoiding equipment failure caused by the heating vehicle falling with the piston rod 3, and ensuring the efficient, stable and safe operation of the heating vehicle.

[0026] The bottom surface of the support block 7 is slidably connected to the upper part of the base 1. The width of the bottom surface of the support block 7 is greater than the width of the slide groove 8. Setting the bottom surface width of the support block 7 to be greater than the width of the slide groove 8 enables the support block 7 to move stably on the base 1, while the base 1 can provide sufficient support force to the support block 7.

[0027] A pressure sensor 9 corresponding to the locking block 5 is installed on the upper surface of the support block 7. The pressure sensor 9 is connected to an external control terminal. By setting the pressure sensor 9, the pressure between the locking block 5 and the support block 7 can be monitored. When an internal leakage fault occurs in the hydraulic cylinder 2, the pressure sensor 9 can detect a sharp increase in the pressure between the locking block 5 and the support block 7. External personnel can judge whether the hydraulic cylinder 2 has malfunctioned by the pressure value monitored by the pressure sensor 9 displayed on the external control terminal, and repair the equipment in time to avoid greater losses caused by misoperation.

[0028] The upper part of the locking block 5 is equipped with a reinforcing rib 10 that is connected to the piston rod 3. By setting the reinforcing rib 10, the strength between the locking block 5 and the piston rod 3 can be improved, thereby improving the stability of the device.

[0029] Two sets of guard plates 11 are installed on the upper part of the base 1. The two sets of guard plates 11 are located on both sides of the support block 7. The inner side of the guard plate 11 is slidably connected to the support block 7. The hydraulic cylinder 2 is located between the two sets of guard plates 11 and the two sets of support blocks 7. By setting the two sets of guard plates 11, the two sides of the support block 7 can be supported, thereby preventing the support block 7 from deforming when supporting the heating vehicle and improving the overall strength of the equipment.

[0030] The working process of this utility model is as follows: When using this device to support the heating vehicle, when the heating vehicle reaches the working position, multiple sets of hydraulic cylinders 2 at the bottom of the heating vehicle push the heating vehicle upward through piston rods 3 and outriggers 4, allowing the heating vehicle to release stored heat energy to the heat-using equipment through pipeline connections. At the same time, motor 6 drives screw 12 to rotate, causing two sets of nuts 13 to move towards each other under the action of two sets of oppositely oriented threads on screw 12, so that the top of the support block 7 contacts the bottom of the locking block 5, thereby completing the support and locking of piston rod 3. After the heating vehicle finishes releasing heat, when the staff observes through the external control terminal that the pressure values ​​of the locking block 5 and the support block 7 monitored by the pressure sensor 9 are normal, the motor 6 drives the lead screw 12 to rotate in the opposite direction, causing the support block 7 to move out from the bottom surface of the locking block 5 and release the lock. Then, the hydraulic cylinder 2 drives the piston rod 3 and the heating vehicle support leg 4 to reset the heating vehicle. If the staff observes through the external control terminal that the pressure values ​​of the locking block 5 and the support block 7 monitored by the pressure sensor 9 are abnormal, the staff needs to carry out further maintenance on the equipment in a timely manner.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
