Description

Technical Field

[0001] The present invention relates to a mining concrete mixing and transporting tank truck, in particular to a mining concrete mixing and transporting tank truck applied to the technical field related to concrete transportation. Background Art

[0002] For mining or tunnel excavation, often in a complex environment outdoors, concrete mixing plants are generally set up at a suitable location far outside the mine or tunnel, and then concrete transport tankers can transport the mixed concrete from the mixing plant to the tunnel construction site, realizing long-distance concrete transportation and ensuring the smooth progress of all aspects of tunnel construction. Tank trucks can directly transport concrete to the vicinity of the pouring position in the mine or tunnel, and cooperate with equipment such as concrete pump trucks to achieve flexible material distribution, making it convenient to pour concrete into different parts of the tunnel, such as side walls, vaults, etc., to improve construction efficiency and quality. The temperature of concrete in concrete transport tank trucks is generally controlled between 10℃ and 35℃. This range is determined based on the needs of concrete construction performance and quality control. Too high or too low temperatures may affect the strength and durability of concrete.

[0003] During transportation, the tank body of the tank truck needs to rotate slowly and continuously to keep the concrete in a stirring state to prevent the concrete from solidifying and segregating during transportation, and to ensure that the concrete still has good workability, fluidity and other working properties when it arrives at the construction site. For example, the Chinese patent specification with publication number CN108608579A discloses a small hydraulic mixing transport tank truck suitable for long-distance transportation of concrete.

[0004] In the prior art, some means are also used to maintain the thermal stability of the concrete inside the tank, such as protecting the heat insulation material outside the tank, using a sunshade, a heat preservation cover, or spraying water for cooling, etc., but these means are mainly focused on reducing the impact of the external environment on the temperature of the concrete, for example, the specification of the Chinese patent with the publication number CN117183872A discloses a cooling and anti-collapse concrete tanker. However, during the long-distance mixing process, the long-term mixing and rotation will cause the friction and collision between the concrete and the stirring blades in the tank to cause the temperature of the concrete in the tank to rise, affecting the quality of the concrete, and these external heat insulation means are difficult to discharge the heat in the tank in time, resulting in the phenomenon of heat accumulation in the concrete in this case, which seriously affects its quality. Summary of the invention

A water pump is also installed inside the water tank, and the drainage end of the water pump is communicated with the liquid delivery pipe mouth. The return pipe is located above the liquid delivery pipe, and the liquid delivery pipe corresponds to the liquid guide port at the head of the tank body.

[0007] In the above-mentioned mining concrete mixing and transport tank truck, an intelligent temperature control system is added inside the tank body to regulate the temperature of the concrete inside the tank body, reduce the temperature change of the concrete caused by the continuous rotation of the tank body, and maintain the concrete at a relatively stable temperature to ensure its quality and strength during use.

[0010] As a further improvement of the present application, the outer end of the supporting plate away from the tank body is fixedly connected with an outer convex plate, and a receiving groove is opened inside the outer convex plate and inside the supporting plate. An elastic bellows is provided in the receiving groove, one end of the elastic bellows is fixed and communicated with the pressure sealing plate, and the other end of the elastic bellows is fixed and communicated with the corresponding return liquid pipe or liquid delivery pipe.

DETAILED DESCRIPTION

[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1-2As shown, a mining concrete mixing and transport tank truck comprises a front end 1, a front frame assembly 2 installed behind the front end 1, and a rear frame assembly 3 connected to the end of the front frame assembly 2, a safety fence 301 is fixedly installed at the edge of the upper end of the rear frame assembly 3, two bearing plates 302 are fixedly connected to the front end of the safety fence 301, and the two bearing plates 302 correspond to the front and rear ends of the tank body 4 respectively, four tugboats 402 are installed on the upper end of the rear frame assembly 3, and the four tugboats 402 are all located on the inner side of the safety fence 301, and a tank body 4 is also provided on the rear frame assembly 3, and the outer ends of the front and rear sides of the tank body 4 are fixedly connected to support rings 401, and the four tugboats 402 are grouped in pairs and contact the two support rings 401 respectively. When the tank body 4 rotates, the tugboats 402 can be used as support points and roll with the support rings 401, thereby assisting the stable rotation of the tank body 4, so that it is not easily affected by excessive friction when rotating.

[0020] like Figure 4-5 A planetary reducer 41 is installed at the center of one end of the tank body 4 close to the front of the vehicle 1, and the end of the tank body 4 away from the front of the vehicle 1 is rotatably connected with a circular cover plate through a slewing support structure 42, and the lower end of the circular cover plate is fixedly connected to the upper end of the rear frame assembly 3 through a fixing rod, and a feed hopper 43 is fixedly connected to the upper right end of the circular cover plate, and a discharge port 44 is fixedly connected to the lower right end of the circular cover plate, and the feed hopper 43 and the discharge port 44 both penetrate the circular cover plate and communicate with the interior of the tank body 4, and a sealing door is provided on the mouth of the discharge port 44, and a hydraulic rod 45 is installed at the lower end of the feed hopper 43, and the extended end of the hydraulic rod 45 is fixedly connected to the middle part of the discharge port 44. Through the setting of the slewing support structure 42, when the tank body 4 rotates, the circular cover plate and the feed hopper 43, the discharge port 44 and the hydraulic rod 45 thereon are in a static state and do not rotate together, thereby effectively maintaining the stability of the internal concrete, so that the concrete is not easy to leak from the feed hopper 43 or the discharge port 44 during the rotation of the tank body; It is worth noting that the planetary reducer 41 is used to adjust the rotation speed of the tank body 4, and its power source can be connected to the engine through a well-known transmission, universal joint and drive shaft, and then drive the mixing tank to rotate, so that the engine provides power for it. The specific implementation method is a well-known technology and is not the technical content of the present invention, so it will not be elaborated in detail.

[0021] like Figure 7-8A spiral stirring blade 6 is fixedly connected to the inner wall of the tank body 4, and a temperature sensor is installed on the inner wall of the tank body 4, and the outside of the temperature sensor is covered with a high thermal conductivity material. The outer shell of the tank body 4 is a double-layer structure. The stirring blade 6 includes two mutually fixed mono-oblique sheets 61 and a plurality of inner support columns 62 fixedly connected between the two mono-oblique sheets 61. A spiral flow channel is formed between the two mono-oblique sheets 61, and the spiral flow channel is communicated with the space between the double layers of the tank body 4. The two liquid guide ports 73 are respectively communicated with the head and tail of the spiral flow channel, so that the liquid in the spiral flow channel can circulate with the outside, so as to take away the heat accumulated due to the rotation of the tank body 4.

[0022] like Figure 3 and Figure 6 The front frame assembly 2 and the rear frame assembly 3 are also provided with an intermittent temperature control unit, which includes two liquid guide ports 73 fixedly connected to the outer end of the tank body 4, a water tank 5 fixedly placed on the upper end of the front frame assembly 2, two intermittent joints fixedly connected to the bearing plate 302, and a return pipe 501 and a liquid delivery pipe 502 respectively fixedly connected between the two joints and the water tank 5. An angle sensor is installed on the liquid guide port 73 near the side of the front of the vehicle 1, the water tank 5 contains coolant, and a refrigeration unit is installed on the inner wall of the water tank 5. 5 is also installed inside, the drainage end of the water pump is connected to the mouth of the liquid delivery pipe 502, the return liquid pipe 501 is located above the liquid delivery pipe 502, and the liquid delivery pipe 502 corresponds to the liquid guide port 73 at the head of the tank body 4; during the rotation of the tank body 4, the temperature sensor monitors the temperature change of the concrete in the tank body 4 in real time. When the temperature gradually increases, it indicates that there is a heat accumulation phenomenon. At this time, when the tank body 4 rotates, the control center can understand the position of the liquid guide port 73 under the action of the angle sensor. When the liquid guide port 73 is directly opposite to the intermittent docking head, the tank body 4 is controlled to stop rotating. Fig. 9 At this time, it can be controlled to connect with the liquid guide port 73, so that the intelligent temperature control system is temporarily built, so that the return pipe 501, the liquid delivery pipe 502, the water tank 5 and the internal spiral flow channel are interconnected to form a loop, and then the water pump is controlled to circulate the cooling water in the spiral flow channel in the tank body 4, so that the cooling water with a lower temperature in the water tank 5 enters the tank body 4, thereby achieving the effect of regulating the temperature of the concrete inside the tank body 4.

[0023] It is worth noting that the tank body 4 stops rotating for no more than 3 minutes each time. When the temperature sensor detects that the temperature drops slowly, the frequency of stopping the tank body 4 can be increased, thereby accelerating the circulation efficiency of the internal cooling water and achieving effective regulation of the concrete temperature.

[0024] like Figure 6The intermittent docking joint includes a sealing plate 71 attached to the carrier plate 302, a boss 72 fixedly connected to the end of the sealing plate 71 away from the carrier plate 302, and an elastic gas ring 74 fixedly connected to the end of the boss 72 away from the sealing plate 71. An embedded annular groove 701 is cut on the end surface of the liquid guide port 73 facing outward, and the boss 72 matches the embedded annular groove 701 with each other. The outer end of the carrier plate 302 away from the tank body 4 is fixedly connected to an outer convex plate, and a receiving groove is cut inside the outer convex plate and the carrier plate 302. An elastic bellows 503 is arranged in the receiving groove. One end of the elastic bellows 503 is fixed and communicated with the sealing plate 71, and the other end of the elastic bellows 503 is fixed and communicated with the corresponding liquid return pipe 501 or liquid delivery pipe 502. An electric push rod is connected between the inner wall of the receiving groove in the boss and the sealing plate 71, and the electric push rod is electrically connected to the control room in the front of the vehicle 1. When the intelligent temperature control system needs to be completely built, such as Fig. 9 When the liquid guide port 73 is aligned with the intermittent docking joint, the electric push rod is controlled to extend so that it pushes the sealing plate 71 to move toward the liquid guide port 73 until the boss 72 is embedded in the embedded annular groove 701, and the elastic air ring 74 is squeezed and contacted with the bottom of the embedded annular groove 701, thereby achieving sealing, so that the cooling water can circulate stably in the temporarily constructed cooling circuit.

[0025] In addition, the intermittent conduction of the cooling circuit can make the water pipeline less susceptible to the influence of the rotation of the tank body 4, less likely to cause unidirectional twisting of the pipeline, and less likely to damage the pipeline, while effectively ensuring the stability of the cooling circuit.

[0026] In addition, this solution takes cooling concrete as an example. When transporting concrete in winter, the refrigeration unit in the water tank 5 is replaced with a heating unit, and then water with a certain amount of heat can be circulated inside the tank body 4 as described above to achieve the effect of heating, so that the concrete is not easily affected by excessively low temperatures.

[0027] In the above-mentioned mining concrete mixing and transport tank truck, an intelligent temperature control system is added in the tank body 4 to regulate the temperature of the concrete inside the tank body, reduce the temperature change amplitude of the concrete caused by the continuous rotation of the tank body 4, and maintain the concrete at a relatively stable temperature to ensure its quality and strength during use.

[0028] The second implementation method: Based on the first embodiment, this embodiment adds a guide unit and changes the driving mode of the sealing plate 71, while the rest of the parts remain the same as the first embodiment.

[0029] In this embodiment, no electric push rod is provided, and the sealing plate 71 is made of ferromagnetic material, and the supporting plate 302 is made of electromagnetic material. When a forward current is passed through the supporting plate 302, the two magnetically repel each other, and when a reverse current is passed through the two magnetically attract each other, thereby achieving control of the position of the sealing plate 71 and achieving intermittent on-off control of the joint and the liquid guide port 73, and the liquid guide port 73 and the corresponding supporting plate 302 are commonly connected with a guide unit.

[0030] like Fig.10 The guide unit includes two columns 81 fixedly connected to the carrier plate 302, and an outer ring 82 fixedly connected to the outer end of the liquid guide port 73. The two columns 81 movably penetrate the pressure sealing plate 71 and cooperate with the through hole gap. One of the columns 81 is a hard hollow transparent structure, and a laser rangefinder 801 is fixedly installed on the inner wall of the column 81 close to the carrier plate 302. A groove 802 is cut at one end of the outer ring 82 facing the outside of the tank body 4. When the liquid guide port 73 is coaxially opposite to the intermittent docking joint, the groove 802 is also coaxial with the laser rangefinder 801. When the angle sensor When it is monitored that the liquid guide port 73 is relative to the intermittent docking joint, if there is no offset or the offset is very small, the laser beam emitted by the laser rangefinder 801 falls in the groove 802. At this time, the distance data is consistent with expectations, and the subsequent docking operation can continue. If the deviation is large, the groove 802 and the laser rangefinder 801 will be greatly misaligned, resulting in excessively large data. At this time, it is necessary to control the tank body 4 to continue to rotate and adjust until the data is consistent with expectations. Compared with the first implementation method, the docking accuracy can be effectively improved to ensure that the cooling water circulates stably when needed.

[0031] like Figure 11-12 The mouth of the embedded annular groove 701 is outwardly expanded, and the edge of the extension ring 82 is subjected to an arc-shaped transition treatment. A compensation ring 83 is fixedly connected to the inner wall of the through hole of the pressure sealing plate 71, so that during the docking process between the intermittent docking joint and the liquid guide port 73, the compensation ring 83 is made of elastic material, and the thickness of the compensation ring 83 is not greater than the difference between the maximum diameter and the minimum diameter of the embedded annular groove 701, and there is a certain fault tolerance. When there is a certain offset between the boss 72 and the embedded annular groove 701, part of the edge of the boss 72 will conflict with the inclined inner wall of the embedded annular groove 701 under the action of the magnetic repulsion force. Due to the elasticity of the compensation ring 83 and the arc-shaped transition of the edge of the boss 72, under the extrusion of the magnetic repulsion force, the pressure sealing plate 71 as a whole can be offset to a certain extent, and then it can also be stably embedded in the straight section of the embedded annular groove 701 to achieve sealing, so that it is not easy to leak during water circulation.

[0032] In summary, a split-type intelligent temperature control system is added to the tank body 4 to regulate the temperature of the concrete inside the tank body. When the temperature of the concrete in the tank body 4 is too high, the tank body 4 is controlled to temporarily stop rotating at a certain angle and a cooling circuit is temporarily built without affecting the rotation frequency of the tank body 4, so that the internal cooling circuit is connected, so that the coolant inside is intermittently circulated and replaced, so that the heat generated by the tank body 4 during continuous rotation can be transported to the outside, reducing the temperature change amplitude of the concrete caused by the continuous rotation of the tank body 4, and maintaining the concrete at a relatively stable temperature, ensuring its quality and strength during use. At the same time, due to the split type of the intelligent temperature control system, the tank body 4 is not easy to affect the stability of the cooling circuit during continuous rotation.

[0033] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
