Detailed Description

The following is further detailed by way of specific embodiments:

as shown in fig. 1, the utility model provides a charging trolley, which comprises a main frame 1, an auxiliary frame 2, a hydraulic tappet 3 and a main wheel 4. The bottom of the main frame 1 is connected with a supporting seat 11 which is used for supporting the whole charging trolley. The supporting seat 11 is a structure having an opening in the middle for allowing at least a part of the structure of the subframe 2 to pass through, and may be a closed structure formed by surrounding a plurality of rods, for example, a frame structure formed by connecting four fixing rods end to end, or a non-closed structure, as long as it can support the charging trolley and allow the subframe 2 to pass through. As shown in fig. 1 and 5, at least one slide rail 12 is provided at a side portion of the main frame 1, and the slide rail 12 extends in a longitudinal direction of the main frame, and preferably, two slide rails 12 are symmetrically provided at both sides of the main frame 1.

The bottom of the sub-frame 2 is provided with a base 21, the base 21 is used for bearing a charging barrel, the side part is fixedly connected with a sliding block 22, the sliding block 22 can be connected on the sub-frame 2 through a structural bolt such as a connecting plate, and the sliding block 22 is matched with the sliding rail 12, so that the sub-frame 2 can slide up and down relative to the main frame 1, and the base 21 can be driven to penetrate into or out of the supporting seat 11. As shown in fig. 1, the left two sliders 22 are symmetrically arranged with respect to the right two sliders 22.

As shown in fig. 1 to 4, at least one positioning ring 23 surrounding the charging barrel (not shown) may be further added to the subframe 2 to prevent the charging barrel from tilting or even turning over during transportation and lifting, thereby achieving a limiting effect. As shown in fig. 1, three positioning rings 23 are preferably provided on the subframe 2, more preferably on the upper, middle and lower (lower) portions of the subframe 2, respectively.

As shown in fig. 1 and 6, a hydraulic tappet 3 is installed between the main frame 1 and the sub-frame 2, and has one end connected to the main frame 1 (i.e., a first connection point) and the other end connected to the sub-frame 2 (i.e., a second connection point). From these two connection points it is decided whether the two ends of the hydraulic tappet 3 are fixedly connected or rotatably connected (e.g. hinged). For example, the first connection point and the second connection point are not on the same vertical line, that is, the extending and retracting direction of the hydraulic tappet 3 is not consistent with the moving direction of the subframe 2 (forming an included angle), when the subframe 2 descends, the second connection point moves downwards, the length of the hydraulic tappet 3 is reduced, at this time, the hydraulic tappet 3 has a tendency to rotate, the two connection points must be set to be in a rotatable connection, preferably in a hinged manner, otherwise, the connection points are damaged, and even the lifting function cannot be realized. On the contrary, the first connection point and the second connection point are on the same vertical line, that is, the telescopic direction of the hydraulic tappet 3 is consistent with (parallel to or overlapped with) the moving direction of the subframe 2, when the subframe 2 descends, the second connection point moves downwards, the length of the hydraulic tappet 3 is reduced, at this time, the length of the hydraulic tappet 3 is shortened in the vertical direction, and the hydraulic tappet 3 does not have a rotating tendency, so that two ends of the hydraulic tappet 3 can be fixedly connected, and the movement of the subframe 2 is not hindered.

Hydraulic tappet 3 can realize automatic flexible according to sub vehicle frame 2's the weight of bearing, when sub vehicle frame 2 bore the charging bucket of certain quality promptly, hydraulic tappet 3 is not enough to support the gross weight of the interior silicon material of sub vehicle frame 2, charging bucket and charging bucket, and sub vehicle frame 2 compresses hydraulic tappet 3 downwards, and sub vehicle frame 2 continues to slide downwards until can not recompress hydraulic tappet 3. When the bucket is empty, the lifting force of the hydraulic tappet 3 causes the subframe 2 to slide upwards, and the subframe reaches the highest lifting position of the hydraulic tappet 3 to stop sliding upwards. According to the actual operation condition, the lifting force of the hydraulic tappet 3 is preferably set to be smaller than 1/4 of the gravity when the charging barrel is fully loaded with silicon materials, so that the automatic descending and charging of the auxiliary frame 2 can be realized by loading a certain amount of silicon materials into the charging barrel; when the feeding is completed and the feeding barrel is in an empty barrel, the lifting force of the hydraulic tappet 3 drives the auxiliary frame 2 to slide upwards.

As shown in fig. 2 and 4, the main wheel 4 is arranged on the main frame 1, preferably on the side of the support base 11, which is the back side of the charging trolley, to ensure that the charging trolley can be placed upright, i.e. to prevent the charging bucket from being tilted when the charging trolley is placed. The main wheels 4 may be universal wheels or solid wheels.

As shown in fig. 1 to 4, the main frame 1 is provided with a leg 13, and the bottom of the leg 13 is provided with a secondary wheel 131, wherein the secondary wheel 131 may be a universal wheel or a fixed wheel. As shown in fig. 2 and 4, the legs 13 are located on the back side of the charging trolley so that the secondary wheels 131 are on the same side as the primary wheels 4, i.e. both on opposite sides of the subframe 2, to facilitate movement of the charging trolley. The leg 13 is rotatably connected to the main frame 1, and a fixing rod group 132 for fixing the leg 13, which is fixedly connected by three rods, is provided between the leg 13 and the main frame 1. The fixed rod assembly 132 is a removable structure that can be removed from the charging trolley. The fixing rod set 132 restricts the rotation of the leg support 13 so as not to rotate arbitrarily, so that the operator can store and release the leg support 13 according to the use condition, and when the leg support 13 is required to be used, the operator can rotate the leg support 13 and install the fixing rod set 132 on the leg support 13.

As shown in fig. 2 and 4, in order to facilitate the operator to push and pull the charging trolley, a handle 14 is provided on the main frame 1, and the handle 14 forms a certain angle with the main frame 1, especially an obtuse angle with the back side of the charging trolley, so as not to block the placement of the charging bucket. In order to facilitate the manual accurate control of the lifting condition of the charging barrel, a locking mechanism 141 can be installed on the handle 14, the specific structure is shown in fig. 7, an operator moves a handrail of the locking mechanism 141 downwards to lock the hydraulic tappet 3, otherwise, the hydraulic tappet is unlocked, the hydraulic tappet 3 is manually controlled to extend and retract, namely, the length of the hydraulic tappet 3 is locked, and the auxiliary frame 2 is controlled to slide up and down by one hand.

In use, the charging carriage carrying the charging basket is moved over a pit in the ground near the single crystal furnace, and the base 21 is aligned with the pit, which allows the base 21 carrying the charging basket to descend through the pit. The locking mechanism 141 is opened, the charging barrel for loading silicon materials is larger than the lifting force of the hydraulic tappet 3 due to the total weight, so that the auxiliary frame 2 slides downwards relative to the main frame 1, namely, the part of the auxiliary frame 2 for bearing the charging barrel passes through the supporting seat 11, at the moment, the charging barrel descends, and a part of the charging barrel enters a pit. When the charging barrel is in an empty barrel state (no load), the gravity of the charging barrel is smaller than the lifting force of the hydraulic tappet 3, the charging barrel automatically rises to the top, and the rising position of the charging barrel can be controlled through the locking mechanism 141 in the process.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
