Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment of fire-fighting steel pipes, in particular to a fire-fighting steel pipe quenching device. Background Art

[0002] Fire-fighting steel pipes generally refer to steel pipes used to transport fire-fighting water. In order to increase the service life of fire-fighting steel pipes, workers generally quench the fire-fighting steel pipes. After quenching, workers generally wet the fire-fighting steel pipes with tap water to cool them down. It takes a lot of effort for workers to manually quench fire-fighting steel pipes. At the same time, the process of workers changing the quenching position of fire-fighting steel pipes is more cumbersome, and the residual temperature remaining on the surface of the quenched steel pipe will burn the workers' hands.

[0003] The utility model currently disclosed with the publication number CN217677645U proposes a quenching device, and in particular relates to a fire-fighting steel pipe quenching device. The utility model provides a fire-fighting steel pipe that can quench the fire-fighting steel pipe evenly as required, and can change the quenching position of the fire-fighting steel pipe at intervals, and can quickly cool down the quenched fire-fighting steel pipe as required, thereby reducing the residual heat of the fire-fighting steel pipe from scalding the workers' hands. A fire-fighting steel pipe quenching device includes a frame, a guide rail, a slider, a ring, a cross bar, a connecting plate, a wedge block and a first spring. A guide rail is welded at the bottom of the inner wall of the frame, a slider is slidably provided on the guide rail, a ring is provided on the top of the slider, and cross bars are slidably provided on the left and right sides of the upper rear side of the inner wall of the frame, and connecting plates are provided at the front ends of the two cross bars. The first springs are connected between the outer sides of the two connecting plates and the frame, and the number of the first springs is six. The heating plate and connecting plate of the utility model can quench the fire-fighting steel pipe.

[0004] However, the above-mentioned prior art still has the following deficiencies when used: 1. The continuity of quenching treatment of different steel pipes is poor, that is, after one steel pipe is quenched, it is difficult for another steel pipe to quickly enter the heating station; 2. The cooling treatment efficiency is low, and it mainly cools the queued steel pipes by spraying water. Due to the small volume of the sprayed water, the heat conduction efficiency is low.

[0005] To this end, the utility model provides a fire-fighting steel pipe quenching device. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a fire-fighting steel pipe quenching device to solve the problems raised in the above-mentioned background technology. The utility model has the advantages of faster switching of different steel pipe quenching and higher efficiency of cooling treatment after quenching.

[0007] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a fire-fighting steel pipe quenching device, including a base, a water pool is arranged above the base, a turntable close to one end is arranged on the top of the water pool, a circumferentially evenly distributed suspension shaft is welded on one side of the turntable, a portal frame is arranged on the top of the water pool, a high-frequency heating wire is slidably connected to the bottom of the portal frame and the sliding direction is parallel to the axis of the suspension shaft, and a control combination for controlling the sliding of the high-frequency heating wire is arranged on the portal frame.

[0011] Furthermore, a thermal insulation sleeve is welded to the bottom of the slider, and the high-frequency heating wire is fixedly arranged in the thermal insulation sleeve.

[0012] Furthermore, a support rod is fixedly connected to the outside of the water pool, and a spray rod is rotatably connected to the top of the support rod, and a row of nozzles is provided on the spray rod.

[0013] Furthermore, a support sleeve is welded to the top of the support rod, a damping sleeve is nested in the support sleeve, and the damping sleeve is arranged on the outside of the spray rod.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a fire-fighting steel pipe quenching device, including a base 1, a water pool 2 is arranged above the base 1, cold water is injected into the water pool 2, and a circulating cooling system can be matched to cool the water in the water pool 2, and a turntable 3 is arranged near one end on the top of the water pool 2. The turntable 3 is vertically arranged, and a suspension shaft 4 uniformly distributed in the circumferential direction is welded on one side of the turntable 3. The suspension shaft 4 is located above the water pool 2, and the suspension shaft 4 is used to suspend the steel pipe. When the turntable 3 rotates, each suspension shaft 4 will drive the steel pipe to enter the water pool 2 in turn.

[0023] A door frame 5 is provided on the top of the water pool 2, and a high-frequency heating wire 6 is slidably connected to the bottom of the door frame 5 and the sliding direction is parallel to the axis of the suspension shaft 4. The high-frequency heating wire 6 can quickly heat the steel pipe. A control assembly 7 for controlling the sliding of the high-frequency heating wire 6 is provided on the door frame 5. The high-frequency heating wire 6 is sleeved on the outside of the steel pipe and can fully heat the steel pipe when sliding.

[0024] Specifically, the control assembly 7 includes a lead screw 71, a slider 72 and a control motor 73. The slider 72 is slidably connected to the top of the door frame 5 and is fixedly connected to the high-frequency heating wire 6. The lead screw 71 is rotatably connected to the top of the door frame 5 and is screwed through and connected to the slider 72. The control motor 73 is fixedly arranged on the outside of the door frame 5 and its output shaft is fixedly connected to one end of the lead screw 71. When the lead screw 71 rotates, it drives the slider 72 to move horizontally along the door frame 5 by the screwing action.

[0025] Furthermore, a heat-insulating sleeve 721 is welded to the bottom of the slider 72, and the high-frequency heating wire 6 is fixedly arranged in the heat-insulating sleeve 721. The heat-insulating sleeve 721 plays a role of heat preservation and also has the advantage of preventing operators from being scalded.

[0026] In this embodiment, a support 21 is welded to the bottom of the pool 2, and a transmission shaft 211 is rotatably connected to the top of the support 21. One end of the transmission shaft 211 is welded to the middle of one side of the turntable 3, and a drive motor 8 is fixedly connected to one side of the support 21. The output shaft of the drive motor 8 is fixedly connected to one end of the transmission shaft 211. When the drive motor 8 controls the transmission shaft 211 to rotate, the transmission shaft 211 can drive the turntable 3 to rotate.

[0027] In this embodiment, a support rod 102 is fixedly connected to the outside of the water pool 2, and a spray rod 9 is rotatably connected to the top of the support rod 102. A row of nozzles 91 are provided on the spray rod 9. The nozzles 91 on the spray rod 9 spray water onto the quenched steel pipe. Due to the continuous water spraying, the speed of cooling the steel pipe can be increased. At the same time, the spraying water can also effectively reduce the emission of smoke and reduce water loss.

[0028] Furthermore, a support sleeve 101 is welded to the top of the support rod 102, and a damping sleeve is nested in the support sleeve 101. The damping sleeve is arranged on the outside of the spray rod 9. This arrangement enables the spray rod 9 to adjust the spray direction of the nozzle 91, so that all the sprayed water can be gathered on the quenched steel pipe.

[0029] Working principle: 1. Steel pipe loading: Use a lifting rope to insert the steel pipe from one end of the suspension shaft 4, so that each suspension shaft 4 carries a steel pipe.

[0030] 2. Heating: Control the turntable 3 to rotate so that one of the steel pipes moves to the highest point, then control the lead screw 71 to rotate, the slider 72 slides and drives the high-frequency heating wire 6 to be sleeved on the outside of the steel pipe, and power is supplied to the high-frequency heating wire 6. At this time, the steel pipe is heated, and then control the slider 72 to slide so that the entire steel pipe is in a heated state.

[0031] 3. Quenching: The control slider 72 drives the high-frequency heating wire 6 to separate from the steel pipe, and then controls the turntable 3 to rotate to drive the heated steel pipe into the water pool 2 to achieve quenching. During the quenching process, the nozzle 91 can be controlled to spray water to reduce the amount of smoke. After quenching, the control turntable 3 continues to rotate, and the quenched steel pipe is separated from the water surface and cooled by the spray water. At the same time, the control slider 72 drives the high-frequency heating wire 6 again to heat other steel pipes at the highest position.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
