For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0033] See also Figures 1 to 8 , the present invention provides a technical solution:

[0034] Embodiment 1, a tire-type transporter support cylinder self-detachment warning system, comprises: a transporter body 1, a cylinder housing 3 and a locking mechanism.

[0035] Specifically, a plurality of groups of moving tires 2 are installed at the bottom of the transporter body 1 and are distributed at equal intervals, so as to facilitate the movement of the transporter body 1;

[0036] Secondly, the oil cylinder housing 3 is vertically mounted at the bottom of the transport machine body 1. Figure 1 As shown, the oil cylinder housing 3 is provided with a plurality of oil cylinders which are spaced apart from the mobile tires 2. A telescopic oil cylinder 4 is slidably installed in the inner cavity at the lower end of the oil cylinder housing 3. The telescopic oil cylinder 4 is driven to extend and retract by hydraulic oil. When the telescopic oil cylinder 4 is extended downward, its lower end can be supported on the ground to support the transporter body 1 and prevent the transporter body 1 from being displaced, thereby improving the stability of the transporter body 1. A jacking mechanism is horizontally installed in the inner cavity at the lower end of the telescopic oil cylinder 4, such as Figure 5 As shown, the jacking mechanism includes two symmetrically distributed and synchronously reversely sliding horizontal jacks 434, a vertical jack 421 is arranged between the two horizontal jacks 434, and the vertical jack 421 is driven downward by the oil pressure in the inner cavity of the oil cylinder housing 3, and the vertical jack 421 drives the horizontal jack 434 to slide horizontally, and the vertical jack 421 drives the horizontal jack 434 to slide horizontally. Figure 5 and Figure 6 As shown, when the vertical push rod 421 slides downward, the vertical push rod 421 squeezes the two horizontal push rods 434 at the same time and drives the two horizontal push rods 434 to move away from each other and extend to the outside of the telescopic cylinder 4. Since the vertical push rod 421 is driven by the oil pressure in the inner cavity of the cylinder shell 3, the horizontal push rod 434 in the jacking mechanism can slide only when the oil pressure in the inner cavity of the cylinder shell 3 is in a high pressure state. At the same time, the hydraulic oil in the inner cavity of the cylinder shell 3 will also drive the telescopic cylinder 4 to extend; when the telescopic cylinder 4 is in a contracted state, the oil pressure in the inner cavity of the cylinder shell 3 is in a negative pressure state, and the horizontal push rod 434 in the jacking mechanism will not slide.

[0037] Furthermore, the locking mechanism includes a fixed seat 62 fixed to the surface of the cylinder housing 3, and a suspension bracket 64 is horizontally slidably mounted on one end of the fixed seat 62. When the suspension bracket 64 is pushed by the horizontal push rod 434, it can slide horizontally. The suspension bracket 64 is "L"-shaped and the upper end corresponds to the horizontal push rod 434. The lower end of the suspension bracket 64 is buckled on the lower end surface of the telescopic cylinder 4, as shown in FIG. Figure 3 and Figure 4 As shown, when the transport machine body 1 is in a moving state and the telescopic cylinder 4 is in a retracted state, the lower end of the suspension frame 64 can be buckled on the lower end of the telescopic cylinder 4 to suspend the telescopic cylinder 4. If the telescopic cylinder 4 is passively extended (i.e., falls) due to its own sealing problem, the locking mechanism can limit the telescopic cylinder 4 to prevent the telescopic cylinder 4 from falling to the ground and causing damage. However, when the telescopic cylinder 4 is actively extended by oil pressure, the oil pressure will first drive the jacking mechanism to work, and the horizontal push rod 434 will push the suspension frame 64 open, thereby releasing the suspension of the telescopic cylinder 4 by the suspension frame 64, thereby ensuring that the telescopic cylinder 4 can be extended normally, thereby achieving support for the transport machine body 1.

[0038] In order to further supplement the structure of the locking mechanism, the locking mechanism of the present application also includes an annular hoop 6 fixedly sleeved on the outer side of the lower end of the cylinder housing 3, and the lower surface of the annular hoop 6 is fixedly connected with a suspension plate 61, and the lower end of the suspension plate 61 is fixedly connected to a fixed seat 62. The fixed seat 62 is configured as a hollow structure with an opening at one end, and an avoidance groove 621 corresponding to the suspension bracket 64 is opened at one end of the lower surface of the fixed seat 62. The setting of the avoidance groove 621 is used to avoid collision between the suspension bracket 64 and the fixed seat 62 when it slides horizontally.

[0039] In order to remind the staff when the telescopic cylinder 4 suddenly falls, the present application also has a sliding block 63 slidably installed in the inner cavity of the fixed seat 62, such as Figure 4 and Figure 7 As shown, the sliding block 63 can only slide horizontally in the inner cavity of the fixed seat 62, and a thrust spring 631 is arranged between the sliding block 63 and the bottom of the groove of the fixed seat 62, and the thrust spring 631 provides a thrust to push the sliding block 63 to reset. The lower end of the suspension frame 64 is provided with an anti-collision notch 643 to avoid collision between the lower end of the suspension frame 64 and the horizontal top rod 434. The upper end of the suspension frame 64 is fixedly installed with a horizontally arranged plug block 641, and the plug block 641 is slidably inserted into the inner cavity of the sliding block 63, as shown in FIG. Figure 7As shown, the suspension frame 64 relies on the plug block 641 to maintain a plug-in connection with the sliding block 63. The lower surface of the plug block 641 is provided with a supporting rubber pad 642 and a proximity switch 8. The setting of the supporting rubber pad 642 increases the friction between the plug block 641 and the sliding block 63 on the one hand to prevent the plug block 641 from separating from the sliding block 63. On the other hand, the plug block 641 can compress the supporting rubber pad 642 to a certain extent in the vertical direction, thereby realizing the vertical displacement of the plug block 641. An alarm electrically connected to the proximity switch 8 is installed on the transporter body 1. When the telescopic cylinder 4 passively falls, the suspension frame 64 is squeezed by the telescopic cylinder 4 and drives the plug block 641 to move downward. At this time, the proximity switch 8 is squeezed by the plug block 641 and the alarm starts to work, thereby being able to remind the staff.

[0040] In order to prevent the telescopic cylinder 4 from being separated from the cylinder housing 3, the present application further has an annular cover 31 fixedly arranged at the lower end opening of the cylinder housing 3, and the annular cover 31 is movably sleeved on the outer side of the telescopic cylinder 4, and a piston 44 is fixedly connected to the outer side of the upper end of the telescopic cylinder 4, and a sealing ring is arranged between the piston 44 and the inner wall of the cylinder housing 3, such as Figure 3 and Figure 4 As shown, the annular cover 31 is used to limit the sliding of the piston 44 in the inner cavity of the cylinder housing 3 to prevent the piston 44 from being separated from the inner cavity of the cylinder housing 3, thereby preventing the telescopic cylinder 4 from being separated from the cylinder housing 3.

[0041] In order to drive the vertical push rod 421 to slide, the present application also has an oil passage 41 opened inside the telescopic oil cylinder 4, and the upper end opening of the oil passage 41 is connected to the inner cavity of the oil cylinder housing 3, such as Figure 5 As shown, the hydraulic oil in the inner cavity of the cylinder housing 3 can enter the inner cavity of the oil channel 41. A vertical slide groove 42 is opened at the lower end of the oil channel 41. The vertical push rod 421 is slidably installed in the inner cavity of the vertical slide groove 42 and the lower end is set to be a frustum. When the oil pressure in the inner cavity of the cylinder housing 3 increases, the hydraulic oil enters the inner cavity of the oil channel 41 and can drive the vertical push rod 421 to slide downward. The upper end of the vertical push rod 421 is fixedly connected with a sealing slider 422 adapted to the vertical slide groove 42. A sealing ring is arranged between the sealing slider 422 and the inner wall of the vertical slide groove 42. The sealing slider 422 is arranged to prevent the hydraulic oil in the inner cavity of the oil channel 41 from leaking from the lower end of the telescopic cylinder 4.

[0042] In order to drive the vertical push rod 421 to reset, the present application also has a reset spring 423 sleeved on the outer side of the vertical push rod 421, and the upper and lower ends of the reset spring 423 respectively press against the lower surface of the sealing slider 422 and the lower inner wall of the vertical slide groove 42. The reset spring 423 is set to reset the vertical push rod 421. When the hydraulic oil pressure in the inner cavity of the cylinder housing 3 is reduced or is in a negative pressure state, the vertical push rod 421 can slide upward.

[0043] In order to drive the horizontal slide 43 to reset, the present application also has a horizontal slide 43 opened at the lower end of the vertical slide 42, and horizontal sliders 431 are slidably installed at both ends of the inner cavity of the horizontal slide 43, and two horizontal push rods 434 are respectively fixed to the side of the two horizontal sliders 431 away from each other. Figure 5 and Figure 6 As shown, the horizontal slider 431 can only slide horizontally in the inner cavity of the horizontal slide groove 43, thereby driving the horizontal push rod 434 to slide horizontally, so that the horizontal push rod 434 is extended to the outside of the telescopic cylinder 4 or is received in the telescopic cylinder 4. The outer side of the horizontal push rod 434 is sleeved with a thrust spring 435, and the two ends of the thrust spring 435 respectively press against one side of the horizontal slider 431 and the inner wall of the end of the horizontal slide groove 43. The setting of the thrust spring 435 is used to reset the horizontal slider 431 and the horizontal push rod 434, and receive the horizontal push rod 434 into the inner cavity of the horizontal slide groove 43.

[0044] In order to simultaneously drive the two horizontal sliders 431 to slide in opposite directions, the present application also has a beveled groove 432 on the upper side of the two horizontal sliders 431 close to each other, and an arc groove 433 is vertically opened at the lower end of the beveled groove 432. The truncated cone-shaped lower end of the vertical push rod 421 is inserted from top to bottom into the circular hole formed by the two arc grooves 433. Figure 5 and Figure 6 As shown, when the vertical push rod 421 slides downward, the truncated cone-shaped lower end of the vertical push rod 421 can squeeze the two horizontal sliders 431 at the same time, so that the two horizontal sliders 431 slide away from each other, thereby extending the two horizontal push rods 434 to the outside of the telescopic cylinder 4 at the same time, and then can push the suspension bracket 64 to release the suspension of the telescopic cylinder 4 by the suspension bracket 64, so as to prevent the suspension bracket 64 from affecting the normal and active extension of the telescopic cylinder 4.

[0045] In order to increase the contact area between the telescopic cylinder 4 and the ground, the present application also has a connecting ball 7 disposed below the telescopic cylinder 4, and a stepped connecting block 71 is fixedly connected to the upper surface of the connecting ball 7. Figure 4 As shown, the connection block 71 is fixedly connected to the telescopic cylinder 4 by bolts, a support foot 5 is arranged below the connection ball 7, a connection column 51 is fixedly connected to the upper surface of the support foot 5, a spherical hinge support 52 is fixedly connected to the upper end of the connection column 51, and the spherical hinge support 52 is arranged to be a hollow structure with an opening at the top, and the connection ball 7 is rotatably installed in the inner cavity of the spherical hinge support 52, as shown in FIG. Figure 2 As shown, the support leg 5 can be installed below the telescopic cylinder 4 through the hinge between the spherical hinge support 52 and the connecting ball 7, so as to increase the contact area between the lower end of the telescopic cylinder 4 and the ground, and prevent the local area of ​​the ground from sinking due to excessive force. At the same time, the support leg 5 can be tilted and rotated at a certain angle around the connecting ball 7 to adapt to different ground terrains.
