Description

Technical Field

[0001] The invention relates to the technical field of transport vehicle chassis, in particular to a special chassis for an underground diesel engine trackless blasting material transport vehicle. Background Art

[0002] Underground diesel trackless blasting equipment is a blasting device that moves on wheels. It is widely used because it does not require pre-laid tracks. However, because it is more troublesome to move and has a slow travel speed, when using trackless blasting equipment, it is necessary to use a transport vehicle to transport it to a designated location and then transport it back after use.

[0003] At present, the patent with announcement number CN113306476A discloses a special chassis for underground diesel trackless blasting material transport vehicles, including a body and a chassis, a surface of the body is fixedly installed with a surface of the chassis, a support groove is opened on a surface of the chassis, a support frame is fixedly installed in the support groove, the support frame is a field-shaped structure, a surface of the support frame is respectively provided with a temperature sensor and a vibration sensor, and the temperature sensor and the vibration sensor are in close contact with the base of the body; by setting a heat dissipation device, a ventilation pipe is fixedly installed in the ventilation groove, the ventilation pipe is an L-shaped structure, one end of the ventilation pipe is fixedly installed with the base of the body, and the other end of the ventilation pipe is connected to the outside of the chassis. The air is connected, and the inner wall of the ventilation duct is coated with thermal conductive paint. When the temperature detected by the temperature sensor exceeds a certain range, the first hydraulic cylinder is driven to extend, pushing one end of the heat dissipation pipe out of the other end of the ventilation duct. The wind driven during driving enters the heat dissipation pipe through the heat dissipation port, contacts the blades of the driving wheel, thereby pushing the blades to rotate the driving wheel, and absorbs the heat from the bottom of the car body through the thermal conductive paint on the inner wall of the ventilation duct. The air circulation is increased by rotating the driving wheel and the heat sink, thereby accelerating the heat dissipation of the car body and preventing the car body temperature from being too high and affecting the internal items. The problem that the existing chassis is generally connected to the car body, the bottom of the box is airtight, and affects the heat dissipation inside the car body is achieved.

[0004] However, the following problems still exist in the use of the current special chassis for blasting equipment transport vehicles:

[0005] The above-mentioned special chassis for blasting material transport vehicles lacks a structure for fixing blasting materials during use. Therefore, when trackless blasting materials are placed on the chassis, since the bottom of the blasting materials is a wheel structure, during transportation, the blasting materials will move due to inertia due to acceleration or deceleration of the transport vehicle. At this time, they will collide with the inner surface of the car, causing deformation of the car and damage to the blasting materials. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a special chassis for an underground diesel engine trackless blasting material transport vehicle. Through a linkage structure, when blasting materials enter the interior of the vehicle, the ventilation function at the bottom of the vehicle compartment is automatically turned on, and through the closing of the tailgate, the blasting materials are limited in position to avoid collision due to inertia.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figure 1-Figure 10 The present invention provides a technical solution: a special chassis for underground diesel engine trackless blasting material transport vehicle, comprising a supporting chassis 1, a compartment for rainproof protection of underground diesel engine trackless blasting material is fixedly installed on the upper end thereof, and a rotating tailgate plate is arranged on the upper end of the rear side of the supporting chassis 1, a square groove is opened on the compartment, and a limited slider 2 is slidably arranged in the square groove, a push plate 3 is fixedly installed on the limited slider 2, the lower end of the push plate 3 is in contact with the upper surface of the supporting chassis 1, a motor 5 is fixedly installed on the push plate 3, and the output end of the motor 5 is connected to the first bevel gear 6 through a rotating shaft, and The second bevel gear set 7 is meshed with each other on both sides of the lower end of the first bevel gear 6, and a receiving screw 8 is fixedly installed on the second bevel gear set 7. A driving slider 9 is fitted on the pushing plate 3, and a threaded hole is opened in the middle position of the driving slider 9, and the driving slider 9 is connected to the receiving screw 8 through the threaded hole, and the receiving screw 8 is rotatably connected with the pushing plate 3. A first rotating plate 10 is rotatably installed on the driving slider 9, and a bonding plate 11 is rotatably installed on the first rotating plate 10. Two groups of the first rotating plate 10 are symmetrically arranged about the center of the bonding plate 11, and the bonding plate 11 is bonded to the front of the transport vehicle.

[0031] When it is necessary to transport blasting materials with different head lengths, the motor 5 starts to work, because the output end of the motor 5 is connected to the first bevel gear 6, and the first bevel gear 6 is meshed with the second bevel gear set 7. Because the second bevel gear set 7 is fixedly installed with a receiving screw 8, the receiving screw 8 starts to rotate, driving the slider 9 to have a threaded hole in the middle position. At this time, as the receiving screw 8 rotates, the slider 9 starts to move, because the receiving screw 8 is symmetrically arranged with two screws about the center of the first bevel gear 6, and the thread structures arranged on the two receiving screws 8 are opposite. Therefore, as the two receiving screws 8 rotate, the two driving sliders 9 starts to move in the direction of approaching or moving away from each other, and because the first rotating plate 10 is rotatably installed on the driving slider 9, as the first rotating plate 10 rotates, the bonding plate 11 starts to move, that is, the bonding plate 11 starts to move in the direction of approaching the pushing plate 3 or moving away from the pushing plate 3, until the bonding plate 11 is adjusted to a suitable position (the suitable position is when the blasting material is moved to the supporting chassis 1, the pushing plate 3 is pushed to make the bonding plate 11 fit with the front of the transport vehicle, and the pushing plate 3 moves to the specified position at this time, that is, it is ensured that the pushing plate 3 is in the same position after each movement), which can effectively avoid the collision between the front of the blasting material and the front of the transport vehicle.

[0032] A connecting spring 4 is slidably installed in the square groove, and the connecting spring 4 is fixedly installed on the limiting slider 2, a fixing plate 12 is fixedly installed on the pushing plate 3, and a wind control plate 13 is fixedly installed on the fixing plate 12, a first ventilation groove 24 is opened on the wind control plate 13, a second ventilation groove 25 is opened in the middle position of the supporting chassis 1, a square guide groove is opened on the upper surface of the supporting chassis 1, two protective slide plates 14 are symmetrically arranged on the lower surface of the wind control plate 13, the outer surface of the protective slide plate 14 is set to be smooth, and the protective slide plate 14 is slidably connected to the supporting chassis 1 through the guide groove opened on the supporting chassis 1, the second ventilation groove 25 opened on the supporting chassis 1 is composed of a large square groove in the middle position of the second ventilation groove 25, a small square groove on the upper surface of the second ventilation groove 25 and a cylindrical groove connected to the side of the supporting chassis 1, and the lower surface of the wind control plate 13 is in contact with the upper surface of the supporting chassis 1.

[0033] As the blasting material is lifted to a specified height by the lifting structure (the lifting structure is an existing lifting machine, which includes but is not limited to existing devices such as lifting forklifts, jacks, screw lifts, etc.), the blasting material begins to move onto the supporting chassis 1 under the drive of the diesel engine. At this time, the wheels of the blasting material travel on the supporting chassis 1 (the width between the wheels is greater than the width of the wind control plate 13) until the front of the blasting material fits with the pushing plate 3 and pushes the pushing plate 3. At this time, the pushing plate 3 begins to move under the action of the limiting slider 2. Because the connecting spring 4 is fixedly installed on the limiting slider 2, the connecting spring 4 begins to be stretched and deformed. Because the pushing plate 3 is connected to the bonding plate 11 through the receiving screw 8 and the first rotating plate 10, the bonding plate 11 begins to move in the direction close to the front of the transport vehicle until it is tightly fitted with the front of the transport vehicle (a pressure sensor is provided on the bonding plate 11. When it reaches When a certain pressure value is reached, an alarm will be triggered to remind that the specified position has been reached). Because a fixed plate 12 is fixedly installed on the push plate 3, the fixed plate 12 drives the wind control plate 13 connected thereto to move, that is, the wind control plate 13 begins to slide along the upper surface of the support chassis 1, and the protective slide plate 14 installed at the lower end of the wind control plate 13 also begins to slide along the support chassis 1 until the first ventilation groove 24 opened on the wind control plate 13 and the second ventilation groove 25 opened on the support chassis 1 are in the same vertical line. At this time, the upper end of the support chassis 1 and the upper end of the wind control plate 13 can be ventilated, that is, the interior of the car can be ventilated. Explosive materials are dangerous goods and need to be kept in a safe state during transportation. Ventilation can help reduce the temperature and humidity in the car and reduce the safety risks that may be caused by high temperature or humid environment. At the same time, proper ventilation can also help prevent the generation of static electricity, further ensuring transportation safety.

[0034] An additional plate 15 is fixedly installed at the middle position of the upper surface of the wind control plate 13, and a fixed slide bar 16 is fixedly installed on the additional plate 15, a guide slider 17 is slidably provided on the fixed slide bar 16, a second rotating plate 18 is rotatably installed on the guide slider 17, and a push-out plate 19 is rotatably installed on the second rotating plate 18, an electric telescopic rod 20 is fixedly installed on the push-out plate 19, and a tire positioning rod 21 is fixedly installed on the electric telescopic rod 20, a pushing support rod 23 is fixedly installed on the guide slider 17, the second rotating plate 18 forms a rotating mechanism with the guide slider 17 through a first rotating shaft installed at its upper end, and the second rotating plate 18 forms a rotating mechanism with the push-out plate 19 through a second rotating shaft installed at its upper end, and a support sleeve 22 is symmetrically fixedly installed on the additional plate 15, and the support sleeve 22 and the push-out plate 19 are connected to each other.

[0035] When the blasting equipment is moved to the designated position in the carriage, the tailgate of the carriage is closed, and the tailgate begins to fit with the push support rod 23, and the push support rod 23 is pushed. Figure 7The two guide sliders 17 are divided into a left slider and a right slider according to the positional relationship. Because the push support rod 23 is fixedly mounted on the right slider, the right slider begins to be pushed, that is, the second rotating plate 18 rotatably mounted on the right slider begins to rotate. As the second rotating plate 18 rotates, the support sleeve 22 begins to support and guide the push-out plate 19 (the second rotating plate 18 is rotatably mounted on the push-out plate 19, and the support sleeve 22 is composed of two sleeves that slide against each other, and one sleeve is fixedly mounted on the mounting plate 15, and the other sleeve is fixedly mounted on the push-out plate 19. At this time, as the push-out plate 19 moves, and the left slider also starts to be pulled and slide), because the guide slider 17 is fixedly mounted with a return spring 31, at this time the return spring 31 begins to be squeezed and deformed, and the push-out plate 19 begins to move toward the direction close to the tire of the blasting equipment, and then the electric telescopic rod 20 starts to work, because the electric telescopic rod 20 is fixedly mounted with a tire positioning rod 21, the tire positioning rod 21 begins to move toward the direction close to the tire of the blasting equipment until it is tightly fitted with the side of the tire of the blasting equipment, at this time, the blasting equipment can be limited to avoid the blasting equipment from moving and colliding due to inertia during subsequent transportation.

[0036] A dustproof plate 26 is fitted on the side of the supporting chassis 1, and a limiting plate 27 is fixedly installed on the surface of the dustproof plate 26, and the limiting plate 27 is set as a "7"-shaped plate structure, the limiting plate 27 and the limiting rotating plate 28 are connected to each other, the limiting rotating plate 28 and the damping bearing 29 constitute a rotating mechanism, and the damping bearing 29 is fixedly installed on the supporting chassis 1, and extension plates 30 are symmetrically arranged on the left and right sides of the upper surface of the wind control plate 13, and the fixed slide rod 16 is fixedly installed between the two extension plates 30, and a return spring 31 is arranged on the outside of the fixed slide rod 16, one end of the return spring 31 is fixedly installed on the mounting plate 15, and the other end of the return spring 31 is fixedly installed on the guide slider 17.

[0037] The air entering the car compartment is filtered through the dustproof plate 26, which can effectively ensure the quality of the incoming air. When the dustproof plate 26 is blocked, the limit rotating plate 28 is turned forcefully (under the action of the damping bearing 29, the stability of the limit rotating plate 28 can be guaranteed to a large extent, that is, a certain amount of force needs to be applied to the limit rotating plate 28 when the limit rotating plate 28 is rotated). At this time, the limit rotating plate 28 begins to move away from the limiting plate 27 until the limit rotating plate 28 is no longer in contact with the limiting plate 27. Then the dustproof plate 26 can be pulled so that the dustproof plate 26 is no longer in contact with the side of the supporting chassis 1. The dustproof plate 26 can be disassembled, replaced or cleaned to ensure the air intake speed.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
