Anti-overturning device for pump truck and pump truck

Abstract

The present disclosure relates to an anti-tipping device for a pump truck and a pump truck. The pump truck comprises a traction member and a counterweight assembly. The counterweight assembly is movably arranged on a side of the pump truck away from a material distribution side of the pump truck and is connected to the pump truck by the traction member to apply a force to the pump truck away from a tipping direction. The force can at least partially offset the tipping force of the pump truck when distributing material, i.e. the combined weight of the boom and the load on the boom, thereby reducing the risk of tipping of the pump truck when distributing material.

Description

Technical Field

[0001] This disclosure relates to the field of engineering machinery technology, specifically to an anti-tipping device for a pump truck and the pump truck itself. Background Technology

[0002] Heavy construction machinery is frequently used on various construction sites for various construction operations. Among them, pump trucks are a relatively common type of machinery. A pump truck typically consists of a turntable and a boom mounted on the turntable for placing concrete.

[0003] In related technologies, in some application scenarios, concrete pump trucks need to place the boom facing the rear of the vehicle and tend to be horizontal when placing materials. Due to the excessive weight of the boom and the excessive load on the boom, the material placement in some areas may be restricted. If material is placed in these areas, the concrete pump truck is prone to a great risk of tipping over. Summary of the Invention

[0004] The purpose of this disclosure is to provide an anti-tipping device for a pump truck and a pump truck in order to at least partially solve the related technical problems.

[0005] To achieve the above objectives, according to a first aspect of this disclosure, an anti-tipping device for a pump truck is provided. The anti-tipping device includes: a traction member; and a counterweight assembly movably disposed on a side opposite to the fabric side of the pump truck and connected to the pump truck via the traction member, for applying a force to the pump truck opposite to the tilting direction.

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

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

[0008] Optionally, the anti-rollover device further includes a tensioning assembly disposed on the pump truck, the tensioning assembly being connected to one end of the traction member and used to tension the traction member.

[0009] Optionally, the traction component is constructed as a steel wire rope, the steel wire rope being wound around the pulley assembly, and the tensioning assembly includes:

[0010] A drum is rotatably mounted on the turntable of the pump truck via a fixed frame. One end of the wire rope is connected to the boom, and the other end is connected to the drum.

[0011] A driving component, which is connected to the drum, is used to drive the drum to rotate in order to tension the wire rope.

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

[0013] Optionally, the wheelset further includes:

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

[0015] The third fixed pulley is connected to the counterweight body via the second mounting bracket.

[0016] Optionally, the second fixed pulley and the third fixed pulley are located on opposite 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] The portion of the traction component located between the second fixed pulley and the pump truck is parallel to the portion of the traction component located between the third fixed pulley and the pump truck;

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

[0019] Optionally, the second fixed pulley is height-adjustably mounted on the first mounting bracket, and the third fixed pulley is height-adjustably mounted on the second mounting bracket.

[0020] Optionally, the first mounting bracket and / or the second mounting bracket are provided with a plurality of mounting holes arranged at intervals along the vertical direction.

[0021] According to a second aspect of this disclosure, a pump truck is provided. The pump truck includes the anti-tipping device described above.

[0022] The above-described technical solution, namely the anti-tipping device for pump trucks disclosed herein, includes a traction component and a counterweight assembly. When the pump truck is working, the counterweight assembly is arranged on the side opposite to the material placement side of the pump truck, that is, the opposite side of the material placement side of the pump truck boom. The traction component connects the counterweight assembly to the pump truck. By utilizing the cooperation between the traction component and the counterweight assembly, a force opposite to the tilting direction can be applied to the pump truck to at least partially offset the tilting force (i.e., the resultant force of the boom's own weight and the boom's load) when the pump truck is placing material, thereby reducing the risk of the pump truck tilting when placing material.

[0023] Furthermore, the technical solution described in this disclosure enables pump trucks equipped with the anti-tipping device to adapt to various construction sites. Specifically, when the boom is placing material, the anti-tipping device can be positioned appropriately as needed, allowing the counterweight assembly to apply a force opposite to the tipping direction to the pump truck via the traction component, thus preventing the pump truck from tipping over. Therefore, the anti-tipping device improves the site adaptability of the pump truck. In addition, the anti-tipping device also avoids the problem of limited material placement due to excessive boom weight and load in some application scenarios, as in related technologies, thus increasing the material placement range of the pump truck.

[0024] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0033] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0034] In this disclosure, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to the user's position when using the device; "inner" and "outer" refer to the inner and outer contours of the corresponding components; furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another.

[0035] According to the first embodiment of this disclosure, as Figure 1 As shown, an anti-tipping device for a pump truck is provided, applied to pump truck 100. The anti-tipping device may include a traction member 1 and a counterweight assembly 2. The counterweight assembly 2 is movably disposed on one side of the fabric-laying side of the pump truck 100 and connected to the pump truck 100 via the traction member 1, for applying a force to the pump truck 100 opposite to the tilting direction.

[0036] Here, it needs to be clarified that the "pump truck 100's placing side" mentioned above refers to the side that the boom 4 mounted on the pump truck 100 faces when performing the placing operation. (Illustratively, as shown...) Figure 1 , Figure 3 and Figure 4 As shown, the fabric-laying side of the pump truck 100 is the side facing the rear of the pump truck 100 (as indicated by the boom 4), the side facing the body of the pump truck 100 (as indicated by the boom 4), and the side facing the front of the pump truck 100 (as indicated by the boom 4). Therefore, it can be understood that the counterweight assembly 2 provided in this embodiment is movably disposed on one side of the fabric-laying side of the pump truck 100, that is, the side facing away from the fabric-laying side of the pump truck 100. Schematic illustration, as shown... Figure 1 As shown, when the boom 4 is placing material towards the rear of the pump truck 100, the counterweight assembly 2 can be positioned on one side of the front of the pump truck 100; as Figure 3 As shown, when the boom 4 is placing material on one side of the pump truck 100, the counterweight assembly 2 can be positioned on the other side of the pump truck 100; as Figure 4 As shown, when the boom 4 is placing material towards the front of the pump truck 100, the counterweight assembly 2 can be positioned on one side of the rear of the pump truck 100. It can be understood that the counterweight assembly 2 is movably arranged on the ground on the side opposite to the material placement side of the pump truck 100; that is, the counterweight assembly 2 is fixed to the ground in a movable manner, allowing it to be moved and positioned according to different application scenarios and material placement locations. The counterweight assembly 2 can be detachably installed on the pump truck 100 or placed at the construction site as needed.

[0037] To enable those skilled in the art to better understand the working principle of the technical solution proposed in this disclosure, the following will be combined with... Figure 2 The force analysis diagram shown is explained in detail below:

[0038] Taking the concrete pump truck 100 laying material on the side facing the rear as an example. Specifically, when the pump truck 100 is laying material, the weight of the boom 4 and the load on the boom 4 (as shown in G2 in the figure) will cause the pump truck 100 to tip over towards the rear. At this time, the tipping direction mentioned above is the rear direction. To prevent the pump truck 100 from tipping over towards the rear, the operator can set the counterweight assembly 2 at the front of the vehicle and connect the pump truck 100 and the counterweight assembly 2 through the traction component 1. This allows the counterweight assembly 2 to use its own weight (as shown in G1 in the figure) and apply a force opposite to the tipping direction to the pump truck 100 through the traction component 1 (as shown in F1 and F2 in the figure). This force can at least partially offset the tipping force of the pump truck 100 when laying material (i.e., the resultant force G2 of the weight of the boom 4 and the load on the boom 4), thereby reducing the risk of the pump truck 100 tipping over when laying material.

[0039] In some embodiments, the counterweight assembly 2 mentioned above may include a counterweight body 21 and a wheel set 22 disposed on the counterweight body 21. Optionally, the counterweight body 21 may be a counterweight block. Correspondingly, the wheel set 22 may be disposed on the counterweight block to facilitate the winding of the traction member 1. This arrangement allows the counterweight block and wheel set 22 to be moved as a whole according to the required position, which is convenient for operators and avoids unnecessary assembly processes. Of course, the counterweight body 21 mentioned here can also be understood as the ground or any suitable heavy object on the ground. In use, the wheel set 22 can be directly fixed to the ground. However, when the counterweight assembly 2 needs to be moved, this arrangement requires frequent assembly of the wheel set 22 on the ground, which is more cumbersome than the technical solution of disposing of the wheel set 22 on the counterweight block. However, it should be understood that the counterweight body 21 can be any suitable solution, such as stones or iron blocks on the construction site, without any limitations. Those skilled in the art can make reasonable choices according to the actual situation.

[0040] In some applications, the traction member 1 is wound around the wheel set 22, with one end of the traction member 1 connected to the boom 4 of the pump truck 100 and the other end connected to any suitable position on the pump truck 100. This arrangement allows both ends of the traction member 1 to be connected to the pump truck 100 via the wheel set 22. Furthermore, the counterweight body 21 can apply a more uniform force away from the overturning direction to the pump truck 100 through the traction member 1, effectively improving the reliability of the anti-overturning device.

[0041] In some embodiments, to further improve the reliability of the anti-rollover device, the anti-rollover device may also include a tensioning assembly 3 disposed 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 can be connected to either end of the traction member 1. For example, the tensioning assembly 3 can be disposed on the turntable 5 of the pump truck 100, with one end of the traction member 1 connected to the boom 4 and the other end of the traction member 1 connected to the tensioning assembly 3. Alternatively, the tensioning assembly 3 can be disposed on the boom 4, with one end of the traction member 1 connected to the tensioning assembly 3 and the other end of the traction member 1 connected to the turntable 5. However, considering the convenience and reliability of installation, the embodiment mentioned above, which involves disposing of the tensioning assembly 3 on the turntable 5 of the pump truck 100, is the preferred embodiment.

[0042] In some applications, the traction component 1 can be constructed as a wire rope. Correspondingly, the tensioning assembly 3 can include a drum 31 and a drive component 32. During installation, the drum 31 can be rotatably mounted on the turntable 5 of the pump truck 100 via a mounting bracket 33. One end of the wire rope is connected to the boom 4, and the other end is connected to the drum 31, with the wire rope wound around the pulley assembly 22. The drive component 32 is driven and connected to the drum 31 to drive the drum 31 to rotate and tension the wire rope. Optionally, the drive component 32 can be a hydraulic motor; of course, other suitable devices can also be used, without limitation, and those skilled in the art can choose according to actual needs.

[0043] In actual operation, with Figure 1 For example, if the hinge angle between the boom 4 and the turntable 5 increases, meaning the boom 4 needs to move upwards towards the side away from the ground, then the drive unit 32 can drive the drum 31 to rotate clockwise to collect the wire rope and tension it. Conversely, if the hinge angle between the boom 4 and the turntable 5 decreases, meaning the boom 4 needs to move downwards towards the side closer to the ground, then the drive unit 32 can drive the drum 31 to rotate counterclockwise to release the wire rope and tension it.

[0044] It should be noted that the traction component 1 can also be made of other suitable materials, such as a chain. This is only for illustrative purposes, and those skilled in the art can make the selection according to the actual situation.

[0045] Below, we will combine Figure 1 The wheelset 22 mentioned above will be explained in detail.

[0046] In some embodiments, the wheel assembly 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 this technical solution, the first fixed pulley 221 enables one end of the traction member 1 to be connected to the boom 4 of the pump truck 100, and the other end to be connected to the pump truck 100 after passing over the first fixed pulley 221, thus achieving the purpose of connecting both ends of the traction member 1 to the pump truck 100.

[0047] In some applications, the wheel assembly 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 via the first mounting bracket 223. One end of the traction member 1 is connected to the boom 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 applications, the wheel assembly 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 via 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 connect to the pump truck 100.

[0049] In other application scenarios, the wheel assembly 22, in addition to the first fixed pulley 221, may also include a second fixed pulley 222 and a third fixed pulley 224. During installation, the second fixed pulley 222 is connected to the counterweight body 21 via the first mounting bracket 223. The third fixed pulley 224 is connected to the counterweight body 21 via the second mounting bracket 225. One end of the traction member 1 is connected to the boom 4, and the other end can sequentially pass through the second fixed pulley 222, the first fixed pulley 221, and the third fixed pulley 224 to connect with the pump truck 100. In this scenario, through the cooperation between the three fixed pulleys, the traction member 1 can be adjusted to a suitable height via the wheel assembly 22, and a reliable anti-tipping 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, with the second fixed pulley 222 being higher than the third fixed pulley 224. The portion of the traction member 1 located between the second fixed pulley 222 and the pump truck 100 is parallel to the portion of the traction member 1 located between the third fixed pulley 224 and the pump truck 100. Further, the portion of the traction member 1 located between the second fixed pulley 222 and the first fixed pulley 221 is parallel to the portion of the traction member 1 located between the third fixed pulley 224 and the first fixed pulley 221.

[0051] In some embodiments, to facilitate the adjustment of the height of the second fixed pulley 222 on the first mounting bracket 223 and the height of the third fixed pulley 224 on the second mounting bracket 225, so that the second fixed pulley 222 and the third fixed pulley 224 are adjusted to the preferred heights described above, the second fixed pulley 222 can be adjusted in height on the first mounting bracket 223, and the third fixed pulley 224 can be adjusted in height on the second mounting bracket 225. Indicatively, a plurality of mounting holes 226 spaced apart in the vertical direction can be provided on the first mounting bracket 223 and / or the second mounting bracket 225. Using a plurality of spaced mounting holes 226 to achieve height adjustment is cost-effective, simple in structure, and easy for operators to adjust. Of course, the height adjustment method can also be a lead screw, telescopic rod, slide rail, etc., and is not limited here; those skilled in the art can choose according to actual needs.

[0052] To further improve the reliability of this anti-rollover device, such as Figure 5 As shown, multiple wheel sets 22 can also be provided on the counterweight body 21, so that multiple traction members 1 can be wound around the corresponding wheel sets 22 respectively, realizing multiple traction effects on the pump truck 100. Optionally, two wheel sets 22 can be provided, and two traction members 1 can be provided.

[0053] According to a second embodiment of this disclosure, a pump truck 100 is provided. The pump truck 100 includes the aforementioned anti-tipping device. The technical solution described in this disclosure enables the pump truck 100 equipped with the anti-tipping device to adapt to various construction sites. Specifically, when the boom 4 is placing material, the anti-tipping device can be positioned appropriately as needed, so that the counterweight assembly 2 can apply a force opposite to the tipping direction to the pump truck 100 through the traction member 1, preventing the pump truck 100 from tipping over. Therefore, the anti-tipping device improves the site adaptability of the pump truck 100. Furthermore, the anti-tipping device can also avoid the problem of limited material placement due to the weight of the boom 4 and excessive load on the boom 4 in some application scenarios, as in related technologies. Therefore, the anti-tipping device also increases the material placement range of the pump truck 100.

[0054] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

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

[0056] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
