Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit earth and stone transportation, in particular to a foundation pit earth and stone transportation device. Background Art

[0002] At present, during the excavation of foundation pit earth and stone, the vertical transportation of foundation pit earth and stone is mainly carried out by lifting grab. As the excavation depth increases, the working efficiency of the lifting grab continues to decrease, and the lifting grab has serious leakage in the vertical transportation of soft and silty soil with high water content, which does not meet the needs of civilized construction at the construction site. Therefore, it is necessary to use foundation pit earth and stone transportation equipment to transport the soil.

[0003] The existing patent (publication number: CN219383378U) discloses a foundation pit earth and stone transportation device, which first cooperates with the second hinge groove, the limit assembly, the limit mechanism and the third hinge groove to easily and quickly release the limit of the bottom plate, so that the earth and stone inside the foundation pit earth and stone transportation box can be quickly dumped to the designated location, thereby improving the efficiency of dumping earth and stone and enhancing the safety of the device to a certain extent. Secondly, by pulling the two pull plates provided, the limit slide plate can be driven to release the limit of the limit rotating rod, and then the limit rotating rod provided by the limit handle can be rotated to rotate the limit rotating rod out of the third hinge groove, so that the bottom plate can be naturally dropped under the action of gravity, and the earth and stone inside the foundation pit earth and stone transportation box will fall into the interior of the transport vehicle under the action of gravity, thereby improving the efficiency of the device in dumping earth and stone.

[0004] However, the above equipment still has certain shortcomings. During the unloading process, the operator is required to approach the foundation pit earth and stone transport box to release the limit of the bottom pad to realize its overturning and unloading. However, in this process, when the earth and stone are dumped out of the transport box, due to its certain impact force and uncertainty, earth and stone splashing often occurs, and the construction site environment is complex. Such splashing earth and stone poses a considerable safety risk and is very likely to cause harm to personnel close to the operation, seriously endangering the personal safety of the operator, bringing potential safety hazards to the construction, and also affecting the smooth progress of the construction to a certain extent. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a foundation pit earth and stone transportation device to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a foundation pit earthwork and rock transport device, comprising a foundation pit earthwork and rock transport box, wherein a bottom plate is hingedly connected to an outer wall of the bottom end of the foundation pit earthwork and rock transport box, and a locking assembly is installed on an outer wall of the bottom plate on a side away from the hinge axis;

[0007] The locking assembly includes a back plate that is slidably sleeved on the outer wall of one side of the bottom pad, and the upper surface of the back plate is symmetrically fixedly connected with two groups of sliders, and the upper surfaces of the two groups of sliders are fixedly connected with a linkage rod, and a first spring is fixed on both sides of the upper surface of the linkage rod, and the outer walls of the slider are provided with a push-pull groove, and the upper surface of one side of the bottom pad is fixedly connected with a mounting seat, and the upper surface of the mounting seat is sleeved with a mounting cover, and the two ends of the inner wall of the mounting cover are fixedly connected to the sliding rod, and the outer walls of the two groups of sliding rods are slidably mounted with connecting rods, and the connecting rods pass through multiple groups of push-pull grooves, and the outer wall of the connecting rod is symmetrically fixedly connected with multiple groups of clamping rods, and one end of each group of clamping rods is sharp, and the sharp end passes through the mounting cover and extends to the interior of the foundation pit earth and stone transport box.

[0008] By adopting the above technical solution, the abutment plate is first placed in contact with the unloading point and moved downward. When the gravity of the earth and stone in the box causes the transport box to approach, the abutment plate is squeezed, driving the slider and the connecting rod to retract. The first spring is compressed to store force for reset. The retraction of the slider causes the push-pull groove to drive the clamping rod to be pulled out of the clamping hole in the box wall, releasing the fixation of the bottom pad. The bottom pad automatically flips over to unload. When the clamping rod retracts, the second spring is compressed to prepare for reset. This structure uses gravity to automatically unload, avoids the risk of manual operation, improves safety and unloading efficiency, and makes up for the shortcomings of existing equipment.

[0009] Furthermore, the outer wall of the bottom end of the support plate is smooth, and the support plate passes through the mounting seat, and the top end of the first spring contacts the mounting cover.

[0010] By adopting the above technical solution, the outer wall of the bottom end of the abutment plate is rounded to reduce wear on the edges and corners, and improve the smoothness of the abutment plate when contacting the placement point. The first spring can provide power for the slider to extend and reset.

[0011] Furthermore, the outer walls at both ends of the connecting rod are fixedly connected with a sliding sleeve, the sliding sleeve and the sliding rod are slidably connected, and the outer wall of the end of the clamping rod away from the foundation pit earth and stone transport box is fixedly connected with a second spring, and the end of the second spring away from the foundation pit earth and stone transport box is in contact with the installation cover.

[0012] By adopting the above technical solution, the two sets of sliding sleeves and the sliding rod can cooperate to limit and stabilize the linkage rod, ensuring its smooth operation. The second spring can squeeze the clamping rod so that the linkage rod is always in close contact with the inner wall of the push-pull groove, ensuring smooth internal and external extension and contraction.

[0013] Furthermore, the cross-section of the clamping rod is a regular rectangle, and a matching through hole is provided at the contact position between the mounting cover and the clamping rod.

[0014] By adopting the above technical solution, the clamping rod with a rectangular cross-section cooperates with the corresponding through hole on the outer wall of the mounting cover to limit the clamping rod, prevent it from rotating, reduce wear, and ensure normal operation of the equipment.

[0015] Furthermore, the inner wall of the mounting cover is symmetrically fixedly connected with multiple sets of limiting slide bars, and the sliders and the limiting slide bars are slidably connected. The mounting cover is fixed to the mounting seat by multiple sets of bolts, and the outer walls of the mounting cover and the mounting seat are both provided with corresponding internal threaded mounting holes.

[0016] By adopting the above technical solution, multiple sets of limiting slide rods can limit the slider to prevent it from offsetting during telescopic movement. By combining multiple sets of bolts with corresponding internal threaded mounting holes, the mounting cover and the mounting base can be quickly docked and installed, making it easy to repair the equipment when it is damaged.

[0017] Furthermore, matching clamping holes are provided at the contact positions between the outer wall of the foundation pit earth and stone transport box and each set of clamping rods, and a clamping plate is fixedly connected to the outer wall of one end of the bottom plate away from the abutment plate.

[0018] By adopting the above technical solution, the clamping hole can provide an installation space for the clamping rod to be inserted, thereby achieving the locking of the bottom pad.

[0019] Furthermore, a cushion block is fixedly connected to the outer wall of the foundation pit earth and stone transport box on a side away from the abutment plate, and the clamping plate is in contact with the cushion block.

[0020] By adopting the above technical solution, when the bottom plate is flipped open for unloading, the clamping plate contacts the pad, so that the bottom plate can always be kept at a certain angle, so that the bottom plate can automatically close when the foundation pit earth and stone transport box is lowered.

[0021] In summary, the present invention has the following beneficial effects:

[0022] The utility model works by firstly fitting the abutment plate into the unloading point and moving it downward. When the gravity of the earth and stone in the box causes the transport box to approach, the abutment plate is squeezed, driving the slider and the connecting rod to retract. The first spring is compressed to store force for reset. The retraction of the slider causes the push-pull groove to drive the clamping rod to be pulled out from the clamping hole in the box wall, releasing the fixation of the bottom pad, and the bottom pad automatically flips over to unload. When the clamping rod is retracted, the second spring is compressed to prepare for reset. This structure uses gravity to automatically unload, avoids the risk of manual operation, improves safety and unloading efficiency, and makes up for the shortcomings of existing equipment.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] The following describes an embodiment of the present invention based on its overall structure.

[0033] A foundation pit earthwork transportation device, such as Figure 1 - Figure 7 As shown, it includes a foundation pit earthwork transport box 1, the bottom outer wall of the foundation pit earthwork transport box 1 is hinged with a bottom pad 2, and the outer wall of the bottom pad 2 is installed with a locking component on the side away from the hinge axis;

[0034] The locking assembly includes a butt plate 21 that is slidably sleeved on the outer wall of one side of the bottom pad 2. Two groups of sliders 22 are symmetrically fixedly connected to the upper surface of the butt plate 21. The upper surfaces of the two groups of sliders 22 are fixedly connected to the linkage rods 23. First springs 24 are fixed on both sides of the upper surface of the linkage rod 23. Push-pull grooves 221 are opened on the outer walls of the sliders 22. A mounting seat 202 is fixedly connected to the upper surface of the mounting seat 202. A mounting cover 27 is sleeved on the upper surface of the mounting cover 27. Both ends of the inner wall of the mounting cover 27 are fixedly connected to sliding rods 271. Connecting rods 25 are slidably installed on the outer walls of the two groups of sliding rods 271, and the connecting rods 25 pass through multiple groups of push-pull grooves 221. Multiple groups of card rods 26 are symmetrically fixedly connected to the outer walls of the connecting rods 25. One end of each group of card rods 26 is sharp, and the sharp end passes through the mounting cover 27 and extends to the interior of the foundation pit earth and stone transport box 1.

[0035] By first fitting the support plate 21 of the foundation pit earth and stone transport box 1 to the unloading point and moving it downward, since the foundation pit earth and stone transport box 1 is loaded with a large amount of earth and stone and has a large gravity, when the transport box approaches the unloading point, the support plate 21 will be squeezed by the earth and stone and the overall gravity of the transport box. At this time, the support plate 21, the slider 22 and the connecting rod 25 will retract, and at the same time, the first spring 24 will be squeezed, accumulating energy for the subsequent squeezing of the connecting rod 25 and the slider 22 to reset. When the slider 22 moves inward, the push-pull groove 221 will drive the connecting rod 25 and the multiple groups of card rods 26 to retract inward. The clamping rod 26 is pulled out from the clamping hole corresponding to the outer wall of the foundation pit earth and stone transport box 1, releasing the fixed restriction on the bottom pad 2, and utilizing the bottom pad 2 to automatically flip open to realize automatic unloading. Among them, while multiple groups of clamping rods 26 are retracted, the second spring 261 will also be squeezed. After being squeezed, the second spring 261 will store elastic potential energy to prepare for the subsequent outward extension of the clamping rod 26 and reset to insert into the clamping hole. In summary, this structure eliminates the steps of manual unloading. This innovative design greatly improves the personal safety of operators at the construction site and improves the automation and efficiency of the unloading operation.

[0036] See also Figure 2 - Figure 7 The outer wall of the bottom end of the support plate 21 is smooth, and the support plate 21 passes through the mounting seat 202. The top of the first spring 24 contacts the mounting cover 27. By setting the above structure, the utility model has a smooth outer wall of the bottom end of the support plate 21, which can reduce the wear at the corners and improve the smoothness of the support plate 21 when contacting the placement point. The first spring 24 can provide the slider 22 with power to extend and reset.

[0037] See also Figure 4 - Figure 7 The outer walls of both ends of the connecting rod 25 are fixedly connected with a sliding sleeve 251, and the sliding sleeve 251 is slidably connected to the sliding rod 271. The outer wall of the end of the clamping rod 26 away from the foundation pit earth and stone transport box 1 is fixedly connected with a second spring 261, and the end of the second spring 261 away from the foundation pit earth and stone transport box 1 is in contact with the mounting cover 27. By setting the above structure, the utility model can cooperate with the two sets of sliding sleeves 251 and the sliding rod 271 to limit and stabilize the linkage rod 23, thereby ensuring the smoothness of its operation. The second spring 261 can squeeze the clamping rod 26 so that the linkage rod 23 is always in close contact with the inner wall of the push-pull groove 221, ensuring smooth internal and external extension.

[0038] See also Figure 4 - Figure 7The cross-sectional shape of the card rod 26 is a regular rectangle, and a matching through hole is provided at the contact position between the mounting cover 27 and the card rod 26. By setting the above structure, the utility model can limit the card rod 26 by cooperating with the through hole corresponding to the outer wall of the mounting cover 27 to prevent it from rotating, reduce wear, and ensure the normal operation of the equipment.

[0039] See also Figure 4 - Figure 7 The inner wall of the mounting cover 27 is symmetrically fixed with multiple sets of limiting slide bars 272, and the slider 22 is slidably connected to the limiting slide bars 272. The mounting cover 27 is fixed to the mounting base 202 by multiple sets of bolts. The outer walls of the mounting cover 27 and the mounting base 202 are provided with corresponding internal threaded mounting holes. By setting the above structure, the utility model can limit the slider 22 with multiple sets of limiting slide bars 272 to prevent it from deflecting during telescopic movement. By matching multiple sets of bolts with corresponding internal threaded mounting holes, the mounting cover 27 and the mounting base 202 can be quickly docked and installed, which is convenient for maintenance when the equipment is damaged.

[0040] See also Figure 1 - Figure 6 Matching clamping holes are provided at the contact positions between the outer wall of the foundation pit earthwork transport box 1 and each group of clamping rods 26, and the outer wall of the end of the bottom plate 2 away from the abutment plate 21 is fixedly connected with a clamping plate 201. By setting the above structure, the utility model can provide an installation space for the insertion of the clamping rod 26 to achieve the locking of the bottom plate 2.

[0041] See also Figure 2 - Figure 6 The outer wall of the foundation pit earth and stone transport box 1 on the side away from the abutment 21 is fixedly connected with a pad 11, and the clamping plate 201 is in contact with the pad 11. By setting the above structure, the utility model can keep the bottom pad 2 at a certain angle at all times when the bottom pad 2 is flipped open for unloading, so that the bottom pad 2 can automatically close when the foundation pit earth and stone transport box 1 is lowered.

[0042] The working principle of the present invention is as follows: when performing the unloading operation, the support plate 21 of the foundation pit earth and stone transport box 1 is first fitted to the unloading point and moved downward. Since the foundation pit earth and stone transport box 1 is loaded with a large amount of earth and stone, it has a large gravity. When the transport box approaches the unloading point, the support plate 21 will be squeezed by the earth and stone and the overall gravity of the transport box. At this time, the support plate 21, the slider 22 and the connecting rod 25 will retract, and at the same time, the first spring 24 will be squeezed to accumulate energy for the subsequent squeezing of the connecting rod 25 and the reset of the slider 22. When the slider 22 moves inward, the push-pull groove 221 will drive the connecting rod 25 and multiple groups The clamping rod 26 retracts inwardly and is pulled out from the clamping hole at the corresponding position on the outer wall of the foundation pit earth and stone transport box 1, thereby releasing the fixing restriction on the bottom pad 2. The bottom pad 2 is automatically flipped open to realize automatic unloading. Among them, while multiple groups of clamping rods 26 retract, the second spring 261 is also squeezed. After being squeezed, the second spring 261 will store elastic potential energy to prepare for the subsequent outward extension of the clamping rod 26 and reset to insert into the clamping hole. In summary, this structure eliminates the steps of manual unloading. This innovative design greatly improves the personal safety of operators at the construction site and improves the automation and efficiency of the unloading operation.
