The use of the device on level ground is generally similar to that on sloping surface and is simpler, and therefore will not be described in detail.
In addition, the device has two points worth explaining: 1. when the slope is uneven and has smaller concave-convex fluctuation, the device can still be used, and only the lower ends of a plurality of pile foundations 12 can be inserted into the ground, so that the use of the device is not affected. Because even the slope is uneven and has small concave-convex fluctuation, the device can still adjust the plane 32 at the top of the sliding seat 30 and the electronic weighing apparatus body 40 to be in a horizontal state, so the device has good practicability. 2. If the pile foundation 12 is partially inserted into the ground due to the gravity after the articles are put on the electronic weighing apparatus body 40, the positions of the plane 32 at the top of the sliding seat 30 and the electronic weighing apparatus body 40 deviate somewhat and are not in the horizontal state, and at this time, the worker can still control the driving mechanism 50 and the transmission mechanism 60 to work again through the control box 70 so as to adjust the plane 32 at the top of the sliding seat 30 and the electronic weighing apparatus body 40 to the horizontal state again. The worker can operate according to the actual situation.
In one embodiment, a level 33 is also mounted on top of the carriage 30, the level 33 being electrically connected to the control box 70. When the plane 32 on top of the carriage 30 is in a horizontal state, the level 33 will display 0 degrees, so that a worker can quickly know whether the plane 32 on top of the carriage 30 is in a horizontal state or is deviated from the horizontal state by a certain degree.
In one embodiment, the two transmission mechanisms 60 are provided, and the two transmission mechanisms 60 are respectively arranged at two ends of the sliding seat 30, so that two ends of the sliding seat 30 are respectively acted by the transmission mechanisms 60, and the transmission effect is better.
In one embodiment, the arc-shaped plate 20 is provided with an arc-shaped groove 21 penetrating in the longitudinal direction at the middle part, the extending direction of the arc-shaped groove 21 is the same as the extending direction of the arc-shaped plate 20, and the arc-shaped groove 21 divides the arc-shaped plate 20 into two independent parts. An arc-shaped piece 22 is arranged in the arc-shaped groove 21, and the arc-shaped piece 22 is adapted to the arc-shaped groove 21 and fixedly connected with the sliding seat 30. Preferably, the top of the connecting seat 13 is also provided with a receiving groove extending downwards and adapted to the arcuate member 22.
Both ends of the connecting seat 13 are provided with clamping mechanisms 80, and the clamping mechanisms 80 include a first air cylinder 81 and a second air cylinder 82. The first cylinder 81 is transversely arranged on the first side of the arc-shaped piece 22, a first end of the first cylinder 81 is fixedly connected with the connecting seat 13, a first clamping plate 83 is fixedly arranged at the second end of the first cylinder 81, and a first rubber pad 84 is fixedly arranged on the inner side of the first clamping plate 83. The second cylinder 82 is transversely arranged on the second side of the arc-shaped piece 22, a first end of the second cylinder 82 is fixedly connected with the connecting seat 13, a second clamping plate 85 is fixedly arranged at the second end of the second cylinder 82, and a second rubber pad 86 is fixedly arranged on the inner side of the second clamping plate 85. The second cylinder 82 and the first cylinder 81 are electrically connected to the control box 70.
When the level 33 shows 0 degrees, i.e., the plane 32 at the top of the slide 30 is in a horizontal state, the worker controls the first and second cylinders 81 and 82 to extend through the control box 70 until the first and second clamping plates 83 and 85 clamp the arc 22. The positions of the arc-shaped member 22 and the sliding seat 30 are further limited, and the sliding seat 30 cannot deviate due to external force, so that the plane 32 at the top of the sliding seat 30 can be stably kept in a horizontal state, and the stability of the device during operation is further improved.
In addition, when the device is used on a slope surface and an object is placed on the electronic weighing apparatus body 40, the sliding block 61 can form acting force on the screw rod 52 under the conduction of gravity. The design of the clamping mechanism 80 also greatly reduces the force of the slider 61 on the screw 52, thereby protecting the screw 52.
In one embodiment, the base plate 10 is provided with a connection mechanism 90 at both ends, and the connection mechanism 90 includes a cylinder 91, a piston 92, and a connecting rod 93. The cylinder 91 is disposed obliquely, the bottom is hinged with the bottom plate 10, a piston 92 is disposed in the cylinder 91, and the piston 92 is slidably connected with the inner wall of the cylinder 91 and is kept sealed by a sealing ring 98. The piston 92 divides the cylinder 91 into a first cavity 94 and a second cavity 95, the first cavity 94 is located below the second cavity 95, the lower portion of the first cavity 94 is communicated with the outside through a communication port 96, and external threads are formed on the outer wall of the communication port 96. The sealing cover 97 is arranged on the communication port 96, the inner wall of the sealing cover 97 is provided with internal threads, the sealing cover 97 is matched with the communication port 96 through threaded connection, and the sealing cover 97 can seal the communication port 96 when being matched with the communication port 96. The first end of the connecting rod 93 is fixedly connected with the piston 92, and the second end of the connecting rod 93 is hinged with the arc-shaped member 22 after passing through the second cavity 95 and the cylinder 91.
In the use of the present device, if the flat surface 32 of the top of the slide 30 is not in a horizontal state, the sealing cap 97 and the communication port 96 are not fitted together. When the level gauge 33 shows 0 degree, that is, the plane 32 at the top of the slide 30 is in a horizontal state, the worker covers the sealing cover 97, at this time, the first cavity 94 becomes a closed space, the positions of the piston 92 and the connecting rod 93 will not move any more under the action of the atmospheric pressure (similar to the principle of the syringe, when the liquid outlet of the syringe is plugged, the piston 92 cannot be pulled by the external force), so that the positions of the arc-shaped member 22 and the slide 30 are further limited, so that the plane 32 at the top of the slide 30 stably maintains the horizontal state, the stability of the device in working is further improved, and the screw rod 52 is further protected.
In one embodiment, the base plate 10 is a rectangular block-like structure. The number of pile foundations 12 is four, and the four pile foundations 12 are respectively positioned at four corners of the bottom plate 10. Thus, when the lower ends of all pile foundations 12 are inserted into the ground, the base plate 10 is better and more stably fixed on the ground.
In one embodiment, a first end of the guide bar 63 is rotatably coupled to the carriage 30 and a second end of the guide bar 63 is in rolling contact with an inner wall of the guide slot 621.
This design enables the guide groove 621 to rotate on the inner wall of the guide groove 621 while applying a pushing force to the connecting rod 93 when the slider 61 and the guide 62 move left and right. This reduces friction between the connecting rod 93 and the inner wall of the guide groove 621, thereby reducing abrasion of the connecting rod 93 and protecting the connecting rod 93.
