Usually, a pump truck includes a turntable and a boom mounted on the turntable for distributing materials.

[0003] In the related art, in some application scenarios of pump trucks, it is necessary to place the boom toward the rear of the vehicle and in a horizontal position to carry out material distribution. Due to the heavy weight and load of the boom, material distribution in some areas will be restricted. If material distribution is carried out in this area, the pump truck is prone to a great risk of tipping over. Summary of the invention

[0004] The purpose of the present disclosure is to provide an anti-rollover device for a pump truck and a pump truck, so as to at least partially solve the related technical problems.

[0005] In order to achieve the above-mentioned purpose, according to the first aspect of the present disclosure, an anti-rollover device for a pump truck is provided. The anti-rollover device comprises: a traction member; and a counterweight assembly, which is movably arranged on a side away from the material distributing side of the pump truck and connected to the pump truck through the traction member to apply a force on the pump truck away from the rollover direction.

[0006] Optionally, the counterweight assembly includes a counterweight body and a wheel set provided on the counterweight body;

[0007] The traction member is wound around the wheel set, and one end of the traction member is connected to the arm of the pump truck, and the other end is connected to the pump truck.

[0009] Optionally, the traction member is configured as a steel wire rope, the steel wire rope is wound around the wheel set, and the tensioning assembly comprises:

[0010] A drum, wherein the drum is rotatably arranged on the turntable of the pump truck through a fixing frame, one end of the steel wire rope is connected to the arm frame, and the other end is connected to the drum;

[0011] A driving member is drivingly connected to the drum and is used to drive the drum to rotate so as to tension the steel wire rope.

[0012] Optionally, the wheel set includes a first fixed pulley arranged on the counterweight body, and the traction member is wound around the first fixed pulley.

[0013] Optionally, the wheel set further includes:

[0014] A second fixed pulley, the second fixed pulley is connected to the counterweight body via a first mounting bracket; and / or

[0015] A third fixed pulley is connected to the counterweight body through a second mounting frame.

[0016] Optionally, the second fixed pulley and the third fixed pulley are respectively located on both sides of the first fixed pulley, and the height of the second fixed pulley is greater than that of the third fixed pulley, wherein:

[0017] A portion of the traction member located between the second fixed pulley and the pump truck is parallel to a portion of the traction member located between the third fixed pulley and the pump truck;

[0018] A portion of the traction member located between the second fixed pulley and the first fixed pulley is parallel to a portion of the traction member located between the third fixed pulley and the first fixed pulley.

[0019] Optionally, the second fixed pulley is mounted on the first mounting frame in a height-adjustable manner, and the third fixed pulley is mounted on the second mounting frame in a height-adjustable manner.

Therefore, the anti-tipping device improves the site adaptability of the pump truck. In addition, the anti-tipping device can also avoid the problem of limited material distribution due to the deadweight of the boom and excessive load on the boom in some application scenarios as in the related art. Therefore, the anti-tipping device also improves the material distribution range of the pump truck.

[0033] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0034] In the present disclosure, unless otherwise specified, directional words such as "up, down, left, right" generally refer to the position when used by the user; "inside, outside" refer to the inside and outside of the corresponding component contour; in addition, it should be noted that the terms used, such as "first, second", etc., are intended to distinguish one element from another.

[0035] According to the first embodiment of the present disclosure, Figure 1 As shown, an anti-rollover device for a pump truck is provided, which is applied to a pump truck 100. The anti-rollover device may include a traction member 1 and a counterweight assembly 2. The counterweight assembly 2 is movably disposed on one side of the material distributing side of the pump truck 100, and is connected to the pump truck 100 through the traction member 1, so as to apply a force to the pump truck 100 that is away from the rollover direction.

[0036] Here, it should be explained that the material distributing side of the pump truck 100 mentioned above is the side that the boom 4 provided on the pump truck 100 faces when performing material distributing operation. Figure 1 , Figure 3 and Figure 4 As shown in the figure, the material distribution side of the pump truck 100 is respectively the side of the rear of the pump truck 100 facing the boom 4, the side of the body of the pump truck 100 facing the boom 4, and the side of the front of the pump truck 100 facing the boom 4. Then, it can be understood that the counterweight assembly 2 provided in this embodiment is movably arranged on one side of the material distribution side of the pump truck 100, that is, the side away from the material distribution side of the pump truck 100. Schematically, as shown in FIG. Figure 1 As shown, when the boom 4 is distributing materials toward the rear of the pump truck 100, the counterweight assembly 2 can be arranged on one side of the front of the pump truck 100; Figure 3 As shown, when the arm 4 is distributing materials toward one side of the pump truck 100 body, the counterweight assembly 2 can be arranged on the other side of the pump truck 100 body; Figure 4 As shown, when the boom 4 is distributing materials toward the front of the pump truck 100, the counterweight assembly 2 can be arranged on one side of the rear of the pump truck 100. It can be understood that the counterweight assembly 2 can be movably arranged on the ground on the side away from the distributing side of the pump truck 100, that is, the counterweight assembly 2 is movably fixed on the ground, so that the counterweight assembly 2 can be moved to a corresponding arrangement according to different application scenarios and different distributing positions. The counterweight assembly 2 can be detachably mounted on the pump truck 100, or it can be placed at the construction site as needed.

[0037] In order to enable those skilled in the art to better understand the working principle of the technical solution proposed in the present disclosure, Figure 2 The force analysis diagram shown is explained in detail, specifically:

[0038] Take the pump truck 100 as an example of distributing materials on the side facing the rear of the vehicle. Specifically, when the pump truck 100 is distributing materials, the deadweight of the boom 4 and the load of the boom 4 (as shown in G2 in the figure) will cause the pump truck 100 to tip over toward the rear of the vehicle. At this time, the tipping direction mentioned above is the rear direction. In order to prevent the pump truck 100 from tipping over toward the rear of the vehicle, the operator can set the counterweight assembly 2 at the front position of the vehicle, and connect the pump truck 100 and the counterweight assembly 2 through the traction member 1, so that the counterweight assembly 2 can use its own gravity (as shown in G1 in the figure) and apply a force (as shown in F1 and F2 in the figure) to the pump truck 100 that deviates from the tipping direction through the traction member 1. This force can at least partially offset the tipping force of the pump truck 100 when distributing materials (i.e., the combined force G2 of the deadweight of the boom 4 and the load of the boom 4), thereby reducing the tipping risk of the pump truck 100 when distributing materials.

[0039] In some embodiments, the counterweight assembly 2 mentioned above may include a counterweight body 21 and a wheel set 22 arranged on the counterweight body 21. Optionally, the counterweight body 21 may be a counterweight block. Matchingly, the wheel set 22 may be arranged on the counterweight block to facilitate the winding of the traction member 1. Such a setting mode enables the counterweight block and the wheel set 22 to be moved as a whole according to the required position, which is convenient for the operator to operate and avoids unnecessary assembly processes. Of course, the counterweight body 21 mentioned here may also be understood as any suitable weight on the ground or on the ground. When in use, the wheel set 22 may be directly fixed on the ground. However, such a setting mode requires the wheel set 22 to be frequently assembled on the ground when the counterweight assembly 2 needs to be moved, which is more complicated to operate than the technical solution of arranging the wheel set 22 on the counterweight block. However, it should be understood that the counterweight body 21 may be selected as any suitable solution, such as stones, iron blocks, etc. at the construction site, without any restriction, and those skilled in the art may make reasonable choices according to actual conditions.

[0040] In some application scenarios, the traction member 1 is wound around the wheel set 22, and one end of the traction member 1 is connected to the arm 4 of the pump truck 100, and the other end is connected to any suitable position on the pump truck 100. Such a setting scheme can enable both ends of the traction member 1 to be connected to the pump truck 100 through the wheel set 22. Furthermore, the counterweight body 21 can apply a more uniform force away from the tipping direction to the pump truck 100 through the traction member 1, effectively improving the reliability of the anti-tipping device.

[0041] In some embodiments, in order to further improve the reliability of the anti-tipping device, the anti-tipping device may further include a tensioning assembly 3 provided on the pump truck 100. During installation, the tensioning assembly 3 is connected to one end of the traction member 1 and is used to tension the traction member 1. It should be noted that the tensioning assembly 3 may be connected to any end of the traction member 1. For example, the tensioning assembly 3 may be provided on the turntable 5 of the pump truck 100, one end of the traction member 1 is connected to the boom 4, and the other end of the traction member 1 is connected to the tensioning assembly 3. For another example, the tensioning assembly 3 may be provided on the boom 4, one end of the traction member 1 is connected to the tensioning assembly 3, and the other end of the traction member 1 is connected to the turntable 5. However, considering the convenience and reliability of installation, the above-mentioned arrangement of the tensioning assembly 3 on the turntable 5 of the pump truck 100 is a preferred embodiment.

[0042] In some application scenarios, the traction member 1 can be constructed as a wire rope. Matchingly, the tensioning assembly 3 may include a drum 31 and a driving member 32. During installation, the drum 31 can be rotatably set on the turntable 5 of the pump truck 100 through a fixed frame 33, one end of the wire rope is connected to the boom 4, and the other end is connected to the drum 31, and the wire rope is wound around the wheel group 22. The driving member 32 is drivingly connected to the drum 31, and is used to drive the drum 31 to rotate to tension the wire rope. Optionally, the driving member 32 can be selected as a hydraulic motor. Of course, it can also be other suitable devices, which are not limited here, and those skilled in the art can make a selection according to actual needs.

[0043] In actual operation, Figure 1 For example, if the hinge angle between the boom 4 and the turntable 5 increases, that is, the boom 4 needs to move upward toward the side away from the ground, then the driving member 32 can drive the drum 31 to rotate clockwise to store the wire rope and achieve tensioning of the wire rope. Correspondingly, if the hinge angle between the boom 4 and the turntable 5 decreases, that is, the boom 4 needs to move downward toward the side close to the ground, then the driving member 32 can drive the drum 31 to rotate counterclockwise to release the wire rope and achieve tensioning of the wire rope.

[0044] Here, it should be noted that the traction member 1 may also be made of other suitable materials, such as a chain. This is only for illustrative purposes, and those skilled in the art may make a choice according to actual conditions.

[0045] Next, we will combine Figure 1 The wheel set 22 mentioned above will be described in detail.

[0046] In some embodiments, the wheel set 22 may include a first fixed pulley 221 disposed on the counterweight body 21. During installation, the traction member 1 is wound around the first fixed pulley 221. In the present technical solution, one end of the traction member 1 can be connected to the boom 4 of the pump truck 100 through the first fixed pulley 221, and the other end can be connected to the pump truck 100 after passing the first fixed pulley 221, so that both ends of the traction member 1 are connected to the pump truck 100.

[0047] In some application scenarios, the wheel set 22 may include a second fixed pulley 222 in addition to the first fixed pulley 221. During installation, the second fixed pulley 222 is connected to the counterweight body 21 through the first mounting bracket 223. One end of the traction member 1 is connected to the arm 4, and the other end can pass through the second fixed pulley 222 and the first fixed pulley 221 in sequence and be connected to the pump truck 100.

[0048] In some other application scenarios, the wheel set 22 may include a third fixed pulley 224 in addition to the first fixed pulley 221. During installation, the third fixed pulley 224 is connected to the counterweight body 21 through the second mounting bracket 225. One end of the traction member 1 is connected to the boom 4, and the other end can pass through the first fixed pulley 221 and the third fixed pulley 224 in sequence and be connected to the pump truck 100.

[0049] In other application scenarios, the wheel group 22 may include a second fixed pulley 222 and a third fixed pulley 224 in addition to the first fixed pulley 221. During installation, the second fixed pulley 222 is connected to the counterweight body 21 through the first mounting frame 223. The third fixed pulley 224 is connected to the counterweight body 21 through the second mounting frame 225. One end of the traction member 1 is connected to the arm 4, and the other end can pass through the second fixed pulley 222, the first fixed pulley 221 and the third fixed pulley 224 in sequence and be connected to the pump truck 100. In this scenario, through the mutual cooperation between the three fixed pulleys, the traction member 1 can be adjusted to a suitable height through the wheel group 22, and a reliable anti-rollover force can be applied to the pump truck 100 through the counterweight assembly 2.

[0050] Optionally, the second fixed pulley 222 and the third fixed pulley 224 can be controlled to be located on both sides of the first fixed pulley 221, and the height of the second fixed pulley 222 is higher than that of the third fixed pulley 224. The portion of the traction member 1 between the second fixed pulley 222 and the pump truck 100 is parallel to the portion of the traction member 1 between the third fixed pulley 224 and the pump truck 100. Further, the portion of the traction member 1 between the second fixed pulley 222 and the first fixed pulley 221 is parallel to the portion of the traction member 1 between the third fixed pulley 224 and the first fixed pulley 221.

[0051] In some embodiments, in order to facilitate the adjustment of the height of the second fixed pulley 222 on the first mounting frame 223 and the height of the third fixed pulley 224 on the second mounting frame 225, so that the second fixed pulley 222 and the third fixed pulley 224 are adjusted to the preferred heights mentioned above, the second fixed pulley 222 can be controlled to be mounted on the first mounting frame 223 in an adjustable manner, and the third fixed pulley 224 can be mounted on the second mounting frame 225 in an adjustable manner. Schematically, a plurality of mounting holes 226 arranged at intervals in the vertical direction can be provided on the first mounting frame 223 and / or the second mounting frame 225. The method of achieving height adjustment by using a plurality of mounting holes 226 arranged at intervals is low in cost, simple in structure, and convenient for operators to adjust. Of course, the height adjustment method can also be a lead screw, a telescopic rod, a slide rail, etc., which is not limited here, and those skilled in the art can choose according to actual needs.

[0052] In order to further improve the reliability of the anti-tilt device, Figure 5 As shown, a plurality of wheel sets 22 may be provided on the counterweight body 21, so that a plurality of traction members 1 can be wound around the corresponding wheel sets 22, thereby achieving multiple traction effects on the pump truck 100. Optionally, two wheel sets 22 may be provided, and two traction members 1 may be provided.

[0053] According to the second embodiment of the present disclosure, a pump truck 100 is provided. The pump truck 100 includes the above-mentioned anti-rollover device. The technical solution described in the present disclosure enables the pump truck 100 provided with the anti-rollover device to adapt to various construction sites. Specifically, when the boom 4 is laying materials, the anti-rollover device can be set at a suitable position as required, so that the counterweight assembly 2 can apply a force that deviates from the rollover direction to the pump truck 100 through the traction member 1 to prevent the pump truck 100 from rolling over. Therefore, the anti-rollover device improves the site adaptability of the pump truck 100. In addition, the anti-rollover device can also avoid the problem of limited material laying due to the deadweight of the boom 4 and the excessive load of the boom 4 in some application scenarios as in the related art. Therefore, the anti-rollover device also improves the material laying range of the pump truck 100.

[0054] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0055] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0056] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
