Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to a garbage transfer box turning mechanism. Background Art

[0002] The demand for classified processing, compression and transportation of domestic waste is also increasing.

[0003] There are two main processes for compressing garbage before transfer:

[0004] One is the vertical garbage compression process, which dumps the garbage into a vertically placed transfer box, fully utilizes the earth's gravity and the weight of the garbage itself to compress it, and then uses a compactor to perform vertical compaction. In this process, the box is in a vertical state. In the industry's commonly used high-entry and flat-exit vertical stations, a vertical arm truck (or wire rope tractor) is often used to flip the vertical transfer box onto the transfer vehicle frame (such as Figure 1 as shown).

[0005] One is the horizontal garbage compression process, which uses a compressor to push the garbage horizontally into the transfer box for compaction. In this process, the box is always placed in a horizontal state. The industry often uses a hook arm truck to pull the horizontal transfer box onto the transfer vehicle frame.

[0006] The transfer vehicles for the two compression processes are of different types. When there are both vertical and horizontal compression process transfer stations in the sanitation operation service area, in order to unify the types of transfer vehicles, it is necessary to configure a flipping mechanism in the vertical transfer station to flip the vertical garbage transfer box into a horizontal state, and then use a hook arm truck to pull the transfer box onto the transfer vehicle frame.

[0007] At present, more and more medium and large-scale garbage transfer stations choose the high-input and flat-out vertical garbage compression process, which is more conducive to garbage classification, more suitable for large-scale compression and transfer, and has more environmental advantages. The turning mechanism used in the transfer station is generally divided into two categories: one is to place the turning space of the turning mechanism under the compactor, which requires the unloading hall and the transfer hall to be arranged on the same side; the other is to place the turning space of the turning mechanism in the lower space of the unloading hall, which requires the unloading hall and the transfer hall to be arranged on different sides.

[0008] The above two types of turnover mechanisms have special requirements for the building structure. They cannot be directly used in the industry's commonly used vertical station building structure with high inlet and outlet on the opposite side. In this building structure, there is a wall below the discharge port, and the transfer box is erected next to the wall of the discharge port to load domestic waste (such as Figure 1 When the building structure cannot be adjusted for certain projects, such as when renovating an old station or when the building has been completed according to a common vertical station structure, it is impossible to open up a turning space for the turning mechanism. Utility Model Content

[0009] In view of the deficiencies of the prior art, the utility model provides a garbage transfer box turnover mechanism to solve the problem that the prior turnover mechanism has special requirements on the building structure.

[0010] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0011] A garbage transfer box turning mechanism is arranged directly below the compactor, and the turning mechanism comprises:

[0012] Horizontal track, fixedly installed on the floor of the transfer hall;

[0013] A vertical track is fixedly mounted on the vertical wall below the discharge port and connected to the horizontal track to form an L-shaped structure; and

The second rotation center is located at the other end of the flip frame and can move up and down along the vertical track.

[0016] In one embodiment disclosed in the present application, the movement of the first rotation center and the second rotation center is achieved by driving a pair of box turning cylinders;

[0017] The cylinder end of each box turning cylinder is hinged to the ground outside the horizontal track, and the piston rod is hinged to the top of the isosceles triangle support arranged on the turning frame in an inclined upward manner.

[0018] In one embodiment disclosed in the present application, a pair of first supports are hingedly connected to one end of the flip frame, and the hinge point between the first support and the flip frame is the first rotation center;

[0019] A first roller is rotatably provided on each of the first supports, and the first roller is in rolling cooperation with the inner side of the I-beam constituting the horizontal track.

[0020] In one embodiment disclosed in the present application, a pair of second supports are hingedly connected at the other end of the flip frame, and the hinge point between the second support and the flip frame is the second rotation center;

[0021] A second roller is rotatably provided on each of the second supports, and the second roller is in rolling cooperation with the inner side of the I-beam constituting the vertical track.

[0022] In one embodiment disclosed in the present application, the turnover frame is provided with a placement area for fixing the transfer box;

[0023] A pair of locking pins are symmetrically arranged on both sides of one end of the placement area close to the second rotation center;

[0024] Each of the locking pins is driven by a lock box oil cylinder built into the first rectangular cylinder and can be inserted into a lock hole opened on the side of the transfer box.

[0025] In one embodiment disclosed in the present application, a limit block is provided on the flip frame;

[0026] The limit block is located in the middle of one end of the placement area close to the second rotation center, and is used to block the transfer box so that the lock hole on its side is quickly aligned with the lock pin.

[0027] In one embodiment disclosed in the present application, each of the first rectangular columns is vertically connected to a pair of guide columns, and each of the guide columns is slidably connected to a second rectangular column fixedly disposed on the flip frame;

[0028] A box-lifting cylinder is installed between a pair of the second rectangular columns, and the two ends of the box-lifting cylinder are respectively connected to the first rectangular column and the turning frame, and is used to drive the first rectangular column to drive the vertical transfer box to be placed on a base fixed to the ground or detached from it.

[0029] In one embodiment disclosed in the present application, it also includes a pair of auxiliary thrust cylinders fixedly mounted on the inner side of the horizontal track and located at the corner of the vertical wall below the discharge port;

[0030] The piston rod of each auxiliary propulsion cylinder extends horizontally and is used to push the transfer box in a vertical state so that the first rotation center of the turnover frame moves to the right along the horizontal track.

[0033] 2. The base is supported by the fixing of the locking pin and the driving of the box lifting cylinder, which can effectively improve the stability of the transfer box during the garbage loading process.

[0034] 3. When the tipping frame changes from a horizontal state to a vertical state with an empty transfer box, the connecting rod structure composed of the box tipping cylinder and the tipping frame (isosceles triangle support) is just at the dead point. The dead point can be bypassed by the auxiliary push cylinder, thereby reducing the starting torque and selection specifications of the box tipping cylinder and saving costs.

[0050] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0051] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0052] See also Figures 1 to 9 As shown, the utility model provides a garbage transfer box turning mechanism, which is arranged directly below the compactor. The turning mechanism 100 includes:

[0053] The horizontal track 110 is fixedly installed on the floor of the transfer hall;

[0054] A vertical track 120 is fixedly mounted on the vertical wall below the discharge port and connected to the horizontal track 110 to form an L-shaped structure; and

[0055] The turning frame 130 is movably connected between the horizontal track 110 and the vertical track 120, and is used to fix the transfer box 200 and turn it synchronously;

[0056] The flip frame 130 has a first and a second rotation center. The first rotation center is located at one end of the flip frame 130 and can move left and right along the horizontal track 110. The second rotation center is located at the other end of the flip frame 130 and can move up and down along the vertical track 120.

[0057] Specifically, the L-shaped structure formed by the horizontal track 110 and the vertical track 120 is placed at the corner of the vertical wall below the discharge port, which will not affect the hook arm vehicle's hooking and placing operations. When working, the empty transfer box 200 returned to the site is placed on the turning frame 130 in a horizontal state using the hook arm vehicle. After the transfer box 200 is fixed, the turning frame 130 starts to turn under the drive of an external force, and the first rotation center moves leftward along the horizontal track 110 ( Figure 3 and Figure 6 The second rotation center moves downward along the vertical track 120, so that the overturning frame 130 changes from a vertical state to a vertical state with the empty transfer box 200, and finally the empty transfer box 200 is erected on the vertical wall below the discharge port to facilitate the garbage collection vehicle to unload into the empty transfer box 200 through the discharge port; after the empty transfer box 200 is filled with a predetermined amount of garbage to become a heavy transfer box 200, an external force drives the overturning frame 130 to start reverse overturning, the first rotation center moves to the right along the horizontal track 110 and slowly moves away from the corner of the vertical wall below the discharge port, and the second rotation center moves downward along the vertical track 120, so that the overturning frame 130 changes from a vertical state to a horizontal state with the heavy transfer box 200, so that it is convenient to use a hook arm vehicle to pull the heavy transfer box 200 onto the transfer vehicle frame and then transfer it to the garbage disposal site for unloading. That is to say, by flipping the flip frame 130 with two rotation centers between the horizontal track 110 and the vertical track 120, the transfer box 200 can be placed against the wall and transformed between the horizontal state and the vertical state, which makes full use of the space under the compactor without making too many requirements on the building structure. It is compatible with the general building structure of high-inlet and flat-out vertical stations on the opposite sides, and reduces the investment cost and engineering workload of the old station renovation.

[0058] See also Figure 2 to Figure 5 As shown, the movement of the first rotation center and the second rotation center is achieved by driving a pair of box turning cylinders 140. Specifically, the cylinder end of each box turning cylinder 140 is hinged to the ground outside the horizontal track 110, and the piston rod is hinged to the top of the isosceles triangle support 131 provided on the turning frame 130 in an inclined upward manner. When the piston rod of the box turning cylinder 140 is extended or retracted, the turning frame 130 can be pulled to move through the isosceles triangle support 131, so that the first rotation center and the second rotation center move along the horizontal track 110 and the vertical track 120 respectively.

[0059] A pair of first supports 150 are hinged at one end of the turning frame 130, and the hinge point between the first support 150 and the turning frame 130 is the first rotation center; a first roller 151 is rotatably provided on each first support 150, and the first roller 151 rolls with the inner side of the I-beam forming the horizontal track 110. A pair of second supports 160 are hinged at the other end of the turning frame 130, and the hinge point between the second support 160 and the turning frame 130 is the second rotation center; a second roller 161 is rotatably provided on each second support 160, and the second roller 161 rolls with the inner side of the I-beam forming the vertical track 120. When the turning frame 130 turns over, the first roller 151 rolls on the inner side of the I-beam forming the horizontal track 110, and the second roller 161 rolls on the inner side of the I-beam forming the vertical track 120.

[0060] The flip frame 130 is provided with a placement area for fixing the transfer box 200. A pair of locking pins are symmetrically arranged on both sides of one end of the placement area close to the second rotation center. Each locking pin is driven by a locking box cylinder built into the first rectangular cylinder 132 and can be inserted into a locking hole (not shown in the figure) opened on the side of the transfer box 200. When the hook arm vehicle places the empty transfer box 200 returned to the site on the flip frame 130 in a horizontal state, the locking hole on the side of the transfer box 200 is aligned with the locking pin, and then the locking box cylinder is started to push the locking pin out of the first rectangular cylinder 132 and insert it into the locking hole, thereby fixing the transfer box 200.

[0061] In order to quickly align the lock hole and lock pin on the side of the transfer box 200 and improve the positioning accuracy of the hook arm vehicle after placing the transfer box 200, a limit block 133 is provided on the turning frame 130. The limit block 133 is located in the middle of one end of the placement area close to the second rotation center and is used to block the transfer box 200 so that the lock hole and lock pin on its side can be quickly aligned.

[0062] Each first rectangular column 132 is vertically connected to a pair of guide columns, and each guide column is slidably connected to a second rectangular column 134 fixedly arranged on the turning frame 130; a box lifting cylinder 135 is installed between the pair of second rectangular columns 134, and the two ends of the box lifting cylinder 135 are respectively connected to the first rectangular column 132 and the turning frame 130, and are used to drive the first rectangular column 132 to drive the vertical transfer box 200 to be placed on the base 210 fixed to the ground or detached from it. After the turning frame 130 changes from a horizontal state to a vertical state with the empty transfer box 200, the piston rod of the box-lifting cylinder 135 retracts, pulling the first rectangular cylinder 132, thereby driving the empty transfer box 200 to move down and place it on the base 210 to support the empty transfer box 200; after loading garbage to become a heavy transfer box 200, the piston rod of the box-lifting cylinder 135 extends, pushing the first rectangular cylinder 132, thereby driving the heavy transfer box 200 to move up to make it detach from the base 210, preparing for the next step of turning the heavy transfer box 200. That is to say, by fixing the lock pin and driving the box-lifting cylinder 135 to obtain the support of the base 210, the stability of the transfer box 200 during the garbage loading process can be effectively improved.

[0063] In order to reduce the starting torque and selection specifications of the box turning cylinder 140, the above-mentioned garbage transfer box turning mechanism 100 also includes a pair of auxiliary push cylinders 170 fixedly installed on the inner side of the horizontal track 110 and located at the corner of the vertical wall below the discharge port. The piston rod of each auxiliary push cylinder 170 extends horizontally and is used to push the vertical transfer box 200 so that the first rotation center of the turning frame 130 moves to the right along the horizontal track 110. When the turning frame 130 is transformed from a horizontal state to a vertical state with an empty transfer box 200, the connecting rod structure formed by the box turning cylinder 140 and the turning frame 130 (isosceles triangle support 131) is just at the dead point position. Through the push of the auxiliary push cylinder 170, the dead point can be bypassed, thereby reducing the starting torque and selection specifications of the box turning cylinder 140 and saving costs.

[0064] According to the above, the specific steps of the utility model with the transfer box 200 are as follows:

[0065] S01. Use the hook arm vehicle to place the empty transfer box 200 on the turning frame 130. When the roller of the empty transfer box 200 reaches the limit block 133, the lock hole on the side of the transfer box 200 is aligned with the lock pin, the box is placed, and the hook arm vehicle is unhooked;

[0066] S02, the lock box oil cylinder is actuated to drive the lock pin to be inserted into the lock hole on the side of the transfer box 200 to lock the empty transfer box 200 and the turnover frame 130 together;

[0068] S04, the piston rod of the box lifting cylinder 135 is retracted, and the empty transfer box 200 falls along the vertical track 120 until the empty transfer box 200 is stably placed on the base 210;

[0069] S05, the door opening mechanism opens the door of the empty transfer box 200, and then the garbage collection truck unloads the garbage into the empty transfer box 200 through the unloading port, and then the garbage is compressed to a predetermined transfer volume by the compactor to become a heavy transfer box 200, and finally the door is closed (see Figure 7 shown);

[0070] S06, the piston rod of the box lifting cylinder 135 extends to lift the heavy transfer box 200 upward along the vertical track 120 to separate it from the base 210;

[0071] S07, the auxiliary push cylinder 170 is actuated to push the bottom of the heavy transfer box 200 away from the vertical wall below the discharge port;

[0072] S08, the box turning cylinder 140 is activated, the first rotation center moves to the right along the horizontal track 110 and slowly moves away from the corner of the vertical wall below the discharge port, and the second rotation center moves downward along the vertical track 120, so that the turning frame 130 with the heavy transfer box 200 is transformed from a vertical state to a horizontal state (see Figure 6 The reverse transformation process shown and Figure 8 );

[0073] S09, the box locking cylinder is actuated to separate the heavy transfer box 200 and the overturning frame 130;

[0074] S10, the hook arm vehicle arrives in front of the flip mechanism to perform hook box operation (see Fig. 9 As shown), the heavy transfer box 200 is transferred to the garbage disposal site for unloading.
