Description

Technical Field

[0001] The utility model relates to the technical field of coal mine auxiliary transportation equipment, in particular to an improved installation structure of an air intake pressure sensor for a chute car. Background Art

[0002] Bidirectional chute vehicles usually refer to transport vehicles that can travel in both directions on tracks and are used in environments such as mines, tunnels, and underground projects. This type of vehicle is designed to transport materials, equipment, or personnel in narrow spaces and has high flexibility and adaptability. If the intake pressure sensor is damaged, it may cause problems such as unstable idle speed, weak acceleration, difficulty starting, black smoke, and increased fuel consumption. Some intake pressure sensors are fixed with bolts. During the movement of the chute vehicle, the bolts may gradually loosen due to the vibration of the vehicle body. The intake pressure sensor is generally installed on the intake manifold, and some are also between the air filter and the throttle, or after the throttle. The specific location depends on the design of the engine. Some locations will be blocked by the engine and other components of the engine system, making it difficult to remove the sensor.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model

[0033] Please refer to Figures 1 to 7 , in the embodiment of the present utility model, an improved installation structure of the intake pressure sensor for the gob-side entry vehicle includes: an intake pressure sensor body 10; a plurality of limit seats 11, which are respectively slidably connected to two outer walls of the intake pressure sensor body 10; an arc seat 12, which is slidably connected to the inside of the limit seat 11; an L-shaped rod 13, which is movably clamped to the top of the arc seat 12, and a limit sleeve 131 is fixedly connected to the top end of the L-shaped rod 13; a limit module 14, which is arranged inside the limit seat 11 and is used to limit adjacent arc seats 12

[0034] Specifically, by fixing an L-shaped rod 13 on the top of the limiting sleeve 131, the fixing bolt body 20 can be installed after the two limiting seats 11 are connected, and the two L-shaped rods 13 are connected and inserted into the top of the fixing bolt body 20 to complete the quick limiting. The L-shaped rod 13 can be moved up and separated from the fixing bolt body 20 by shifting the two shift blocks 145. There is no need to reciprocate the bolts, and the disassembly and assembly are convenient. The limiting is stable, which can prevent the fixing bolt body 20 from shifting and loosening during operation, so that the fixing effect is better and it is convenient to use.

[0035] Embodiment 1

[0036] like Figure 1-6 As shown, in the present embodiment, two limit frames 101 are symmetrically fixedly connected on both sides of the intake pressure sensor body 10, rectangular rods 111 are fixedly connected on both sides of the top and bottom of the limit seat 11, the rectangular rods 111 are slidably connected to the inside of the adjacent limit frames 101, a protrusion 102 is fixedly connected to one side of the limit frame 101, and a clamping block 112 is fixedly connected to the top and bottom of the limit seat 11, and the clamping block 112 is movably clamped with the adjacent protrusion 102.

[0037] In this embodiment, the rectangular rod 111 is limited by the limit frame 101 to achieve sliding limitation of the two limit seats 11, so that the two limit seats 11 can dock with each other to limit the fixing bolt body 20, and can be laterally moved and separated from the fixing bolt body 20 for easy disassembly. When driving the two limit seats 11 to dock, the two limit seats 11 are positioned by the protrusion 102 to engage the clamping block 112, so that the two limit seats 11 can be fixed in the specified position in advance when there is no fixing bolt body 20 between the limit seats 11, which is convenient for subsequent fixing using the fixing bolt body 20.

[0038] like Figure 7 As shown, in this embodiment, a plurality of plug blocks 113 are fixedly connected to one side of two limit seats 11, and the plug blocks 113 can be movably engaged with adjacent limit seats 11. The opposite sides of the two adjacent limit seats 11 are fixedly embedded with magnetic blocks 114, and the relative magnetic poles of the two adjacent magnetic blocks 114 are different.

[0039] During specific implementation, when docking the two limit seats 11, the two limit seats 11 are clamped together using the insert block 113 to strengthen the connection between the two limit seats 11 and prevent the connection from loosening in the vertical direction. The positions of the two limit seats 11 are firstly auxiliary limited by the mutual attraction of the two magnetic blocks 114 to prevent the two limit seats 11 from separating from each other after the docking is completed and the hands are released, thereby facilitating the subsequent installation and fixation of the fixing bolt body 20.

[0040] Embodiment 2

[0041] On the basis of Embodiment 1, in order to facilitate automatic fixation after the two limit sleeves 131 are clamped with the fixing bolt body 20, the installation and disassembly of the limit seat 11 are made more convenient.

[0042] As Figure 1-5 shown, in this embodiment, an arc-shaped groove 115 is formed in the top of the limit seat 11. A clamping sleeve 132 is slidably connected between the inner walls of the arc-shaped groove 115. The limit sleeve 131 penetrates through the adjacent clamping sleeve 132 and is slidably connected therewith. A first chute 116 and a second chute 117 which communicate with each other are formed in the limit seat 11. The arc-shaped seat 12 is slidably connected inside the first chute 116. The limit module 14 includes: a ratchet rack 141 which is slidably connected inside the second chute 117. A limit block 121 is fixedly connected to the outer wall of the arc-shaped seat 12, and the limit block 121 can be movably clamped with the ratchet rack 141; two sliders 142 which are respectively slidably connected to the top and bottom ends of the second chute 117, and both of the two sliders 142 are fixedly connected with the ratchet rack 141; two return springs 144 which are fixedly connected to one side of the ratchet rack 141, and one end of the return spring 144 is fixedly connected with the limit seat 11; two round rods 143 which are fixedly connected to an inner wall of the second chute 117, the round rod 143 penetrates through the ratchet rack 141 and is slidably connected therewith, and the round rod 143 penetrates through the adjacent return spring 144; two dial blocks 145 which are fixedly connected to the bottom of the ratchet rack 141, and both of the two dial blocks 145 penetrate through the limit seat 11 and are slidably connected therewith; a connecting rod 146 which is fixedly connected between the bottom ends of the two dial blocks 145. A plurality of balls 1421 are rotatably connected to the opposite sides of the two sliders 142.

[0043] In specific implementation, the arc groove 115 is used to limit the position of the card sleeve 132 to ensure the direction of the top of the limiting sleeve 131, so as to limit the angle of the L-shaped rod 13, the slide groove 116 is used to slide and limit the arc seat 12, and the slide groove 2 117 is used to slide and limit the ratchet bar 141. The two sliders 142 cooperate to slide and limit the ratchet bar 141. After the two limiting sleeves 131 are connected, the two limiting sleeves 131 are rotated to align them with the top of the fixing bolt body 20, and then pressed down for clamping. During the process, the limiting block 121 moves the ratchet bar 141 to compress the reset spring 144, and the ratchet bar 141 allows the limiting block 121 to move downward, but Through the engagement of the ratchet bar 141 and the limit block 121, the ratchet bar 141 does not allow the arc seat 12 to move up, thereby ensuring that the two limit sleeves 131 are engaged with the top of the fixing bolt body 20, and the two limit seats 11 wrap the fixing bolt body 20 to complete the limiting. At this time, the two L-shaped rods 13 need to move up and disengage from the fixing bolt body 20, and then adjust the angles of the two L-shaped rods 13 to separate the limit seats 11 to complete the disassembly from the fixing bolt body 20. Therefore, the limiting is stable enough, and the ball 1421 is convenient for reducing the friction between the slider 142 and the limit seat 11, so that the ratchet bar 141 can be driven to move more smoothly when the shift block 145 is used to drive the ratchet bar 141 from the bottom of the ratchet bar 141.

[0044] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
