AI Technical Summary
During bridge construction, when engineering vehicles are towed on a slope, the safety is poor due to the breakage of the tow rope, making it difficult to effectively prevent the vehicles from moving down the slope.
The system employs a combination of eccentric chucks and vertical piles. The eccentric chucks are installed at both ends of the engineering vehicle and engage with the vertical piles. The eccentric structure, under the action of gravity, keeps the gap in contact with the plane of the vertical pile, thus preventing the vehicle from moving downhill.
This improves the safety of engineering vehicles when towing on slopes, ensuring that the vehicle does not move downhill in the event of a rope breakage, and enhancing the stability and safety of the towing process.

Description
Technical Field
[0001] This utility model relates to the field of engineering vehicle technology, and more specifically, to an engineering vehicle safety device and an engineering vehicle. Background Technology
[0002] During bridge construction, there are situations where construction is carried out along a slope. It is necessary to use a traction system to pull engineering vehicles from the bottom of the slope to the top. However, since the traction force required for engineering vehicles is large, if the traction rope of the traction system breaks, the engineering vehicle will move downhill, which is unsafe. Utility Model Content
[0003] The problem this invention addresses is: how to improve the safety of engineering vehicles pulling on slopes.
[0004] To address the aforementioned problems, this utility model provides a safety device for engineering vehicles, comprising an eccentric chuck and a post. The eccentric chuck is rotatably mounted on the engineering vehicle and is distributed at both ends in the width direction of the engineering vehicle. The post is fixed to a slope. The eccentric chuck has a notch, which includes a first side and a second side. The post includes a first plane and a second plane that are perpendicular to each other. The first plane is parallel to the slope, and the second plane faces the uphill direction. The first side abuts against the first plane, and the second side abuts against the second plane.
[0005] Optionally, the length of the first side is greater than the length of the second side.
[0006] Optionally, the bottom of the pile is used to be inserted into the slope and fixed to the slope by anchor bolts.
[0007] Optionally, the eccentric chuck is made of steel.
[0008] Compared with the prior art, the engineering vehicle safety device of this utility model has an eccentric chuck that allows the eccentric chuck to deflect at both ends in the width direction of the engineering vehicle. This ensures that the notch on the eccentric chuck always faces the post fixed on the slope. The first side of the notch abuts against the first plane on the post that is parallel to the slope, and the second side of the notch abuts against the second plane on the post that faces the uphill direction. The eccentric chuck is then locked to the post. The post not only prevents the rotation of the eccentric chuck but also prevents its movement, thereby preventing the engineering vehicle from moving downhill and improving the safety of the engineering vehicle when traction on a slope.
[0009] On the other hand, this utility model also provides an engineering vehicle, including a vehicle body and an engineering vehicle safety device as described above. The eccentric chuck of the engineering vehicle safety device is rotatably mounted on the vehicle body, and the uprights of the engineering vehicle safety device are distributed at both ends in the width direction of the vehicle body. The eccentric chuck is used to engage with the uprights.
[0010] Optionally, the engineering vehicle further includes a traction pulley and a connecting rope. The traction pulley is installed at the front end of the vehicle body and swings relative to the vehicle body. One end of the connecting rope is connected to the traction pulley, and the other end is connected to the first side of the eccentric chuck. The traction pulley is used to pull the eccentric chuck so that there is no interference between the eccentric chuck and the pile.
[0011] Optionally, the engineering vehicle further includes a pivot shaft, which is rotatably disposed at the front end of the vehicle body. The two ends of the pivot shaft extend from the vehicle body along the vehicle width direction and are respectively connected to the eccentric chuck. A sleeve is provided on the side of the eccentric chuck near the vehicle body, and the sleeve is fitted onto the pivot shaft to separate the eccentric chuck from the vehicle body.
[0012] Optionally, a limiting ring is provided on the side of the eccentric chuck away from the vehicle body, and the eccentric chuck abuts against the limiting ring and the sleeve.
[0013] Optionally, the limiting ring is sleeved on the rotating shaft and threadedly connected to the rotating shaft.
[0014] Optionally, a limiting plate is also provided on the rotating shaft, and the sleeve abuts between the limiting plate and the eccentric chuck.
[0015] Compared with the prior art, the engineering vehicle of this utility model is rotatably installed on the vehicle body by an eccentric chuck of the engineering vehicle safety device. The uprights of the engineering vehicle safety device are distributed at both ends of the vehicle body in the width direction. The eccentric chuck is used to engage with the uprights. In the event of rope breakage, the vehicle body can be restricted from moving downhill by engaging with the uprights, thereby improving the safety of the vehicle body for traction on slopes.

[0023] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in sequences other than those illustrated or described herein.
[0024] Combination Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a safety device for engineering vehicles, including an eccentric chuck 1 and a pile 2. The eccentric chuck 1 is rotatably mounted on an engineering vehicle 3 and is distributed at both ends in the width direction of the engineering vehicle 3. The pile 2 is fixed on a slope 10. The eccentric chuck 1 is provided with a notch, which includes a first side 11 and a second side 12. The pile 2 includes a first plane 21 and a second plane 22 that are perpendicular to each other. The first plane 21 is parallel to the slope 10, and the second plane 22 is oriented towards the uphill direction. The first side 11 is used to abut against the first plane 21, and the second side 12 is used to abut against the second plane 22.
[0025] Specifically, two eccentric chucks 1 are mounted on the front end of the engineering vehicle 3 via a rotating shaft 6, and are distributed at both ends in the width direction of the engineering vehicle 3. The two eccentric chucks 1 rotate synchronously via the rotating shaft 6. Multiple uprights 2 are fixed on the slope 10 and are distributed at intervals along the length of the vehicle, and the multiple uprights 2 are symmetrically distributed on both sides of the width of the engineering vehicle 3 with respect to the length of the vehicle. On the eccentric chuck 1, a notch is provided at the edge of the eccentric chuck 1, the notch including a first side 11 and a second side 12. The uprights 2 include a vertical first plane 21 and a second plane 22. The first plane 21 is parallel to the slope 10, and the second plane 22 faces the uphill direction. The eccentric chuck 1 has an eccentric structure. After the eccentric chuck 1 is rotated and installed on the engineering vehicle 3, the eccentric chuck 1 can make the notch face downward under the action of gravity, so that the first side 11 can face the slope 10, that is, the first side 11 can face the first plane 21. When the rope breaks, the first side 11 on the two eccentric chucks 1 abuts against the first plane 21 on the same side of the upright pile 2, and the second side 12 abuts against the second plane 22 on the same side of the upright pile 2. The two eccentric chucks 1 and the upright pile 2 on the same side form a "racket"-like structure, thereby preventing the engineering vehicle 3 from moving down the slope.
[0026] Therefore, in this embodiment, the eccentric chuck 1 is configured to deflect at both ends in the width direction of the engineering vehicle 3, so that the notch on the eccentric chuck 1 always faces the post 2 fixed on the slope 10, and the first side 11 on the notch and the first plane 21 on the post 2 parallel to the slope 10 abut against each other, and the second side 12 on the notch abuts against the second plane 22 on the post 2 facing the uphill direction. After this, the eccentric chuck 1 and the post 2 are locked together. The post 2 can not only prevent the eccentric chuck 1 from rotating, but also prevent the eccentric chuck 1 from moving, thereby preventing the engineering vehicle 3 from moving downhill, so as to improve the safety of the engineering vehicle's slope traction.
[0027] In the above embodiment, the eccentric chuck 1 will continuously collide with the pile 2 during the process of traction of the engineering vehicle 3. That is, during the uphill process, the eccentric chuck 1 rotates counterclockwise intermittently. If it is necessary to avoid the eccentric chuck 1 colliding with the pile 2 during the uphill process, the connecting rope 5 described later can be used to connect the eccentric chuck 1 to the traction pulley 4 on the vehicle body.
[0028] Optionally, combined Figure 2 As shown, the length of the first side 11 is greater than the length of the second side 12.
[0029] Specifically, the length of the first side 11 is greater than the length of the second side 12, which makes the contact area between the first side 11 and the first plane 21 greater than the contact area between the second side 12 and the second plane 22. After the eccentric chuck 1 and the pile 2 are engaged, the force on the first side 11 is greater than the force on the second side 12, thereby improving the load-bearing capacity of the first side 11 and improving the engagement stability of the eccentric chuck 1 and the pile 2.
[0030] Optionally, the bottom of the pile 2 is used to be inserted into the slope 10 and fixed to the slope 10 by anchor bolts.
[0031] Specifically, multiple steel bars can be welded to the bottom of the pile 2 so that the pile 2 can be inserted into the slope 10. After the pile 2 is inserted into the slope 10, the pile 2 is then fixed to the slope 10 by anchor bolts.
[0032] Thus, the bottom of the pile 2 is used to insert it into the slope 10 and is fixed to the slope 10 by anchor bolts, thereby achieving double fixation of the pile 2 and improving the stability of the pile 2 on the slope 10.
[0033] Optionally, the eccentric chuck 1 is made of steel.
[0034] Specifically, the eccentric chuck 1 can be a steel plate, and a notch is provided on the eccentric chuck 1 so that the eccentric chuck 1 forms an eccentric structure similar to the shape of a horse's head. When the eccentric chuck 1 is rotated and installed on the vehicle body, the eccentric chuck 1 can deflect under the action of gravity, so that the notch faces downward.
[0035] Thus, by making the eccentric chuck 1 out of steel, the structural strength of the eccentric chuck 1 can be improved, ensuring the stability of the eccentric chuck 1 in use.
[0036] Combination Figure 1 , Figure 2 and Figure 3 As shown, another embodiment of the present invention also provides an engineering vehicle, including a vehicle body and an engineering vehicle safety device as described above. The eccentric chuck 1 of the engineering vehicle safety device is rotatably mounted on the vehicle body, and the uprights 2 of the engineering vehicle safety device are distributed at both ends in the width direction of the vehicle body. The eccentric chuck 1 is used to engage with the uprights 2.
[0037] Specifically, two eccentric chucks 1 are located at the front end of the vehicle body, at both ends in the vehicle width direction, and are rotatably connected to the vehicle body along the same axis. Multiple anchors 2 are located on both sides in the vehicle width direction and fixed to the slope 10 along the vehicle length direction. Due to the structure of the eccentric chucks 1, the notch on the eccentric chucks 1 always faces downwards. During the traction process, even if the anchors 2 interfere with the eccentric chucks 1, causing them to rotate counterclockwise, the notch on the eccentric chucks 1 can still return to its downward position due to gravity. In the event of rope breakage, the eccentric chucks 1 engage with the anchors 2 through the notch, i.e., the first side 11 abuts against the first plane 21, and the second side 12 abuts against the second plane 22, forming a "racket structure" to restrict the vehicle body from moving downhill.
[0038] Thus, the eccentric chuck 1 of the engineering vehicle safety device is rotated and installed on the vehicle body, and the uprights 2 of the engineering vehicle safety device are distributed at both ends in the width direction of the vehicle body. The eccentric chuck 1 is used to engage with the uprights 2. In the event of rope breakage, the vehicle body can be restricted from moving downhill by engaging with the uprights 2, thereby improving the safety of the vehicle body for traction on slopes.
[0039] Optionally, combined Figure 1 and Figure 2 As shown, the engineering vehicle also includes a traction pulley 4 and a connecting rope 5. The traction pulley 4 is installed at the front end of the vehicle body and swings relative to the vehicle body. One end of the connecting rope 5 is connected to the traction pulley 4, and the other end is connected to the first side 11 of the eccentric chuck 1. The traction pulley 4 is used to pull the eccentric chuck 1 so that there is no interference between the eccentric chuck 1 and the pile 2.
[0040] Specifically, the traction pulley 4 includes a wheel frame and a pulley rotatably mounted on the wheel frame. The wheel frame is rotatably mounted on the front end of the vehicle body. When the vehicle body is traction on the slope 10, the steel wire rope of the traction mechanism on the slope passes around the wheel body of the traction pulley 4, causing the traction pulley 4 to rotate upward. As the traction pulley 4 rotates, the traction pulley 4 is connected to the first side 11 through the connecting rope 5, causing the eccentric chuck 1 to rotate upward, so that the lowest position of the eccentric chuck 1 can be located above the pile 2 during the traction process. That is, during the traction process, there is no contact between the eccentric chuck 1 and the pile 2. When the wire rope of the traction mechanism breaks, the traction pulley 4 will deflect downward under the action of gravity, and the connecting rope 5 will no longer be straightened. That is, the traction pulley 4 releases the restriction on the eccentric chuck 1. The eccentric chuck 1 rotates downward under its own weight. When the vehicle moves downhill, the first side 11 of the eccentric chuck 1 abuts against the first plane 21 of the post 2, and the second side 12 abuts against the second plane 22. The eccentric chuck 1 is locked with the post 2 and restricts the vehicle from moving downhill.
[0041] Thus, by installing the traction pulley 4 at the front end of the vehicle body and swinging it relative to the vehicle body, one end of the connecting rope 5 is connected to the traction pulley 4, and the other end is connected to the first side 11 of the eccentric chuck 1, so that the first side 11 deflects toward the traction pulley 4. The setting of the connecting rope 5 enables the traction pulley 4 and the eccentric chuck 1 to deflect synchronously, thereby realizing the linkage between the traction pulley 4 and the eccentric chuck 1. In the event of rope breakage, the eccentric chuck 1 can respond in time under its own weight. When the rope does not break, the connection of the connecting rope 5 to the first side 11 of the eccentric chuck 1, and the deflection of the first side 11, ensures that the lowest position of the eccentric chuck 1 is above the post 2, and also prevents interference between the eccentric chuck 1 and the post 2, avoiding collision between the eccentric chuck 1 and the post 2.
[0042] Optionally, combined Figure 3 As shown, the engineering vehicle also includes a rotating shaft 6, which is rotatably mounted at the front end of the vehicle body. The two ends of the rotating shaft 6 extend from the vehicle body along the width direction and are keyed to the eccentric chuck 1 respectively. A sleeve 7 is provided on the side of the eccentric chuck 1 near the vehicle body. The sleeve 7 is fitted onto the rotating shaft 6 to separate the eccentric chuck 1 from the vehicle body.
[0043] Specifically, an eccentric chuck 1 is installed at each of the two ends of the shaft 6 in the upward direction. The eccentric chuck 1 rotates synchronously with the shaft 6. The sleeve 7 is fitted on the shaft 6 and is located on the side of the eccentric chuck 1 facing the vehicle body. The sleeve 7 makes the eccentric chuck 1 and the vehicle body separated by a certain distance, so as to avoid interference between the rotation of the eccentric chuck 1 and the vehicle body.
[0044] Thus, the two ends of the rotating shaft 6 extend from the vehicle body along the width direction and are keyed to the eccentric chuck 1 respectively. A sleeve 7 is provided on the side of the eccentric chuck 1 near the vehicle body. The sleeve 7 is fitted onto the rotating shaft 6 to separate the eccentric chuck 1 from the vehicle body. The sleeve 7 prevents the eccentric chuck 1 from interfering with the vehicle body during the synchronous rotation of the eccentric chuck 1 and the rotating shaft 6, ensuring the stable use of the eccentric chuck 1.
[0045] Optionally, combined Figure 3 As shown, a limit ring 8 is also provided on the side of the eccentric chuck 1 away from the vehicle body, and the eccentric chuck 1 abuts between the limit ring 8 and the sleeve 7.
[0046] Specifically, the limiting ring 8 is located at the end of the eccentric chuck 1 away from the vehicle body. The limiting ring 8 is sleeved on the rotating shaft 6. The two ends of the eccentric chuck 1 in the axial direction abut against the sleeve 7 and the limiting ring 8, respectively.
[0047] Thus, a limiting ring 8 is also provided on the side of the eccentric chuck 1 away from the vehicle body. The eccentric chuck 1 abuts against the limiting ring 8 and the sleeve 7. The sleeve 7 and the limiting ring 8 can tighten the eccentric chuck 1, thereby limiting the axial movement of the eccentric chuck 1 and ensuring the axial stability of the eccentric chuck 1.
[0048] Optionally, combined Figure 3 As shown, the limiting ring 8 is sleeved on the rotating shaft 6 and threadedly connected to the rotating shaft 6.
[0049] Specifically, the axial cross-sectional shape of the limiting ring 8 can be quadrilateral or circular, and an internal threaded hole is provided at the axial position of the limiting ring 8, and an external thread is provided at the shaft end of the rotating shaft 6. The limiting ring 8 can be connected to the rotating shaft 6 by threads.
[0050] Thus, by fitting the limiting ring 8 onto the rotating shaft 6 and threading it to the rotating shaft 6, the stability of the limiting ring 8 in the axial direction of the rotating shaft 6 can be improved, thereby enhancing the limiting effect of the limiting ring 8 on the eccentric chuck 1.
[0051] Optionally, combined Figure 3 As shown, a limiting plate 9 is also provided on the rotating shaft 6, and the sleeve 7 abuts between the limiting plate 9 and the eccentric chuck 1.
[0052] Specifically, the limiting plate 9, the sleeve 7, and the eccentric chuck 1 are respectively fitted onto the rotating shaft 6. The end face of the limiting plate 9 facing the vehicle body abuts against the vehicle body, the end face of the limiting plate 9 away from the vehicle body abuts against one end of the sleeve 7, and the other end of the sleeve 7 abuts against the end face of the eccentric chuck 1 facing the vehicle body.
[0053] Thus, by having the sleeve 7 abut against the limiting plate 9 and the eccentric chuck 1, the limiting plate 9 can not only separate the sleeve 7 from the vehicle body, but also indirectly increase the contact area between the sleeve 7 and the vehicle body, thereby reducing the friction of the sleeve 7, and at the same time restricting the axial movement of the sleeve 7.
[0054] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
