Description

Technical Field

[0001] This utility model relates to the field of molten metal liquid feeding technology, specifically to a molten metal liquid feeding trough cart. Background Technology

[0002] In industries such as metallurgy and casting, the transfer and pouring of molten metal are critical steps in the production process, and their efficiency and safety directly affect product quality and production continuity. Traditional molten metal discharge trough devices generally suffer from limited mobility and operational flexibility, making it difficult to adapt to the demands of multi-station switching and rapid adjustments in production. They typically can only perform discharge operations in a fixed location, failing to accommodate the switching needs between multiple stations or different production lines. This results in inflexible production line layouts and low production efficiency.

[0003] Chinese patent CN102853673A discloses a portable tubular guide channel device for transferring liquid metal. The device includes a moving mechanism, a telescopic mechanism, and a liquid metal guiding component. Although it uses a telescopic mechanism, it relies on manual operation of the rotary handle and the number of liquid receiving carts is fixed, making it difficult to adapt to the switching needs between multiple workstations or different production lines.

[0004] Chinese patent CN202869274U discloses a mobile guide device for molten non-ferrous metals. The device consists of a movable frame, a guide pipe, etc., and is driven by a stepper motor to move along the track. However, the structure is complex and it is only suitable for the top of a specific smelting furnace, and cannot adapt to the switching needs between multiple workstations or different production lines. Utility Model Content

[0005] This utility model provides a molten metal discharge channel car to solve the problem of low production efficiency caused by the inability of existing flow guiding devices to adapt to the switching between multiple workstations or different production lines.

[0006] To address the aforementioned problems, this utility model provides a molten metal discharge channel cart for guiding molten metal from a furnace to a receiving cart. The cart includes: a base; a support platform mounted on the base, the support platform comprising several first support platforms, second support platforms, and third support platforms; a guide channel mounted on the support platform, the third support platform supporting the lower end of the guide channel; and a receiving cart located below the lower end of the guide channel.

[0007] The above solution, using a segmented support platform structure, enables the adjustment of the guide channel at multiple different workstations, allowing the guide channel to be switched between different workstations or production lines, significantly improving work efficiency. The guide channel can be lifted using the existing rotary lifting device, and with the modular combination of the support platform, the angle of the guide channel can be adjusted to place it at different workstations, thus achieving workstation switching of the guide channel.

[0008] According to one embodiment of the present invention, the aforementioned guide channel includes an arc-shaped channel, a supporting shell disposed at the bottom left side of the arc-shaped channel, and an arc-shaped cover plate disposed at the upper right side of the arc-shaped channel. Through the above solution, the supporting shell stably supports the arc-shaped channel, preventing it from shaking or deforming under the gravity and flow impact of the molten metal, thus ensuring the stability of the guide path. The arc-shaped cover plate effectively prevents the molten metal from splashing out of the guide channel, providing a relatively safe working environment for the operator.

[0009] According to one embodiment of the present invention, the first support platform is used to support the support shell, and the third support platform is used to support the lower end of the arc-shaped groove. Through the above scheme, with stable support, the arc-shaped groove can guide the molten metal liquid according to a predetermined trajectory, so that the molten metal liquid flows into the preset liquid receiving car, thereby improving the quality of the product and the production efficiency.

[0010] According to one embodiment of the present invention, pull rings are fixed on both sides of the middle part of the arc-shaped groove. With the above solution, when it is necessary to move the guide groove between different work positions, hooks, ropes and other tools are used to connect with the pull rings, and the guide groove is moved by lifting equipment to realize the work position switching of the guide groove.

[0011] According to one embodiment of the present invention, pulleys are installed under the base and the liquid receiving cart, and a track is fitted to the bottom of the pulleys. Through the above scheme, the guide effect of the track on the pulleys enables the equipment to move along a predetermined path. A single flow channel cart can move through the track to serve multiple furnaces for liquid guiding, realize equipment sharing, and realize the switching of multiple production lines.

[0012] According to one embodiment of the present invention, at least two of the first support platform and the second support platform are provided, and at least three of the third support platform are provided. Through the above scheme, the first support platform and the second support platform form a multi-point support structure, so that the liquid outlet position of the guide channel points to the liquid receiving vehicle.

[0013] According to one embodiment of the present invention, the liquid receiving cart is provided with at least three liquid receiving tanks. Through the above solution, the three third support platforms can be adapted to meet the needs of different furnace production lines, further realize the switching of multiple production lines, and improve work efficiency.

[0014] According to one embodiment of the present invention, the top of the third support platform is provided with a movable arc-shaped support plate. Through the above solution, the arc-shaped support plate realizes the multi-angle rotation of the guide channel through a structure such as a ball joint or universal joint, which can match the relative position of the liquid outlet of the guide channel and the liquid receiving cart of different work stations. At the same time, it allows the guide channel to achieve direction switching through local adjustment without moving the overall flow channel cart, thus shortening the work station switching time.

[0015] According to one embodiment of this utility model, the contact heights of the first support platform, the second support platform, and the third support platform with the guide channel decrease sequentially. Through this scheme, the decreasing height of the support platforms causes the guide channel to form a preset tilt angle, utilizing gravity to assist the stable flow of the molten metal.

[0016] The technical advantages of this application are as follows:

[0017] This application provides a molten metal unloading trough cart, which adopts a segmented support platform structure to realize the adjustment of the guide trough at multiple different work positions, and realize the switching of the guide trough at different work positions or production lines, significantly improving work efficiency; by using an existing rotary lifting device to lift the guide trough, and in conjunction with the modular combination of the support platform, the direction of the guide trough can be adjusted to place it at different work positions, realizing the switching of the guide trough work positions.

[0023] The following will be combined with the appendix Figures 1-3 The embodiments of the technical solution of this application are described in detail below. The following embodiments are only used to illustrate the technical solution of this application more clearly, and are therefore only examples and should not be used to limit the scope of protection of this application.

[0024] Reference Figures 1-3This utility model provides a molten metal discharge channel cart for guiding molten metal in a furnace 1000 to a receiving cart 4. The molten metal discharge channel cart includes: a base 1, a support platform 2 on the base 1, the support platform 2 including a plurality of first support platforms 201, second support platforms 202, and third support platforms 203; a guide channel 3 on the support platform 2, the third support platform 203 being used to support the lower end of the guide channel 3; and the receiving cart 4 located below the lower end of the guide channel 3.

[0025] The above scheme adopts a three-section support platform 2 structure, which consists of a first support platform 201, a second support platform 202, and a third support platform 203. Different positions of the third support platform 203 correspond to the liquid receiving carts 4 at the bottom, forming different workstations for liquid guiding. The existing rotary lifting device is used to raise the guide channel 3, and the angle of the guide channel 3 is further adjusted. The adjustment range covers different positions of the first support platform 201 and the third support platform 203, realizing the switching of different workstations at the high and low ends of the guide channel 3. This further guides the molten metal liquid in different furnaces 1000 to different liquid receiving carts 4, ultimately realizing the switching of different workstations of the guide channel 3.

[0026] The aforementioned flow guide trough 3 includes an arc-shaped trough 302, a support housing 301 located at the bottom left side of the arc-shaped trough 302, and an arc-shaped cover plate 304 located at the upper right side of the arc-shaped trough 302. Through the above scheme, the support housing 301 stably supports the arc-shaped trough 302, preventing it from shaking or deforming under the gravity and flow impact of the molten metal, thus ensuring the stability of the flow path. The arc-shaped cover plate 304 effectively prevents the molten metal from splashing out of the flow guide trough 3, providing a relatively safe working environment for the operators.

[0027] The first support platform 201 is used to support the support shell 301, and the third support platform 203 is used to support the lower end of the arc-shaped groove 302. Through the above scheme, with stable support, the arc-shaped groove 302 can guide the molten metal liquid according to the predetermined trajectory, so that the molten metal liquid flows into the preset liquid receiving car 4, thereby improving the quality of the product and the production efficiency.

[0028] Pull rings 303 are fixed on both sides of the middle part of the arc-shaped groove 302. With the above solution, when it is necessary to move the guide groove 3 between different work positions, hooks, ropes and other tools are used to connect with the pull rings 303, and the guide groove 3 is moved by a rotating lifting device to realize the work position switching of the guide groove 3.

[0029] Both the base 1 and the liquid receiving cart 4 are equipped with pulleys 5, and the bottom of the pulleys 5 is fitted with a track 6. Through the above scheme, the track 6 guides the pulleys 5 so that the equipment moves along a predetermined path. A single flow channel cart can move through the track 6 to serve multiple furnaces 1000 for liquid guiding, realize equipment sharing, and realize the switching of multiple production lines.

[0030] The first support platform 201 and the second support platform 202 are each provided in at least two, and the third support platform 203 is provided in at least three. Through the above scheme, the first support platform 201 and the second support platform 202 form a multi-point support structure to realize an inclined segmented support structure. The third support platform 203 is arranged at the end so that the liquid outlet of the guide channel 3 points to the liquid receiving vehicle 4.

[0031] The liquid receiving cart 4 is equipped with at least three liquid receiving tanks. Through the above scheme, it can be adapted to the third support platform 203 in three different positions, which can meet the needs of different furnace 1000 production lines, further realize the switching of multiple production lines, and improve work efficiency.

[0032] The top of the third support platform 203 is provided with a movable arc-shaped support plate 2031. Through the above scheme, the arc-shaped support plate 2031 can realize the multi-angle rotation of the guide channel 3 through the ball joint or universal joint and other structures, which can match the relative position of the liquid outlet of the guide channel 3 and the liquid receiving tank of different work stations. At the same time, it allows the guide channel 3 to achieve direction switching through local adjustment without moving the overall flow channel car, thus shortening the work station switching time.

[0033] The contact heights of the first support platform 2012, the second support platform 2022, and the third support platform 2032 with the guide channel 3 decrease sequentially. Through the above scheme, the decreasing height of the support platforms 2 causes the guide channel 3 to form a preset tilt angle, utilizing gravity to assist the stable flow of molten metal.

[0034] Working principle:

[0035] The base 1 and the pulleys 5 installed under the receiving cart 4 cooperate with the track 6 laid on the ground. The entire flow channel cart can move along a predetermined path to different operating positions in the furnace 1000. Molten metal is introduced from the furnace 1000 into the arc-shaped channel 302 of the guide channel 3. The first support platform 201, the second support platform 202, and the third support platform 203 form a segmented support structure, with their heights decreasing sequentially, so that the guide channel 3 forms a preset tilt angle. The tilt angle utilizes gravity to help the molten metal flow stably towards the receiving cart 4 in the arc-shaped channel 302, resulting in smooth discharge and finally flowing out from the end of the guide channel 3.

[0036] When different furnaces 1000 are working, the flow channel car is moved to the position of different furnaces 1000 through the track system to guide the liquid. Before guiding the liquid, a rotary lifting device is used to lift the flow channel 3 as a whole upward, and the liquid flow direction of the flow channel 3 is rotated and adjusted to align with the target liquid receiving car 4. The arc-shaped support plate 203 adapts to the multi-angle rotation of the liquid flow direction of the flow channel 3 through structures such as ball joints or universal joints, so as to accurately align the flow direction with the liquid receiving car 4, thereby realizing the switching of different work positions, shortening the switching time of the liquid receiving car 4, and improving work efficiency.

[0037] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
