Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gasoline engine core sampling machines, specifically a gasoline engine core sampling machine that prevents burns. Background Technology
[0002] Gasoline engine-type coring machines are specialized equipment for core sampling in engineering quality testing and are widely used for core sampling tests on cement concrete and asphalt concrete in highways, docks, and municipal projects. During prolonged operation, the engine temperature, especially near the exhaust stack, can rise significantly, posing a serious safety hazard and posing a risk of burns to operators. Utility Model Content
[0003] To address the problems of the prior art, this invention provides a gasoline engine-type core extractor designed to prevent burns. A protective device is added to the engine exhaust box to prevent workers from being burned at the engine exhaust area.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a gasoline engine-type core extractor for preventing burns, comprising a frame, a gasoline engine fixedly connected to the frame, and a water pump fixedly connected to the frame. The gasoline engine includes an exhaust box fixedly connected to the frame, a protective pipe fixedly connected to the wall of the exhaust box, a water inlet pipe fixedly connected to the first end of the protective pipe, and a water outlet pipe fixedly connected to the second end of the protective pipe. The water outlet pipe is connected to the water pump.
[0005] With the above structural design, the water pump provides cooling water for the core drilling machine, while the water flows through the water pipe through the smoke box, carrying away some of the heat from the smoke box. At the same time, the protective pipe is installed on the smoke box to provide heat insulation and prevent workers from being accidentally burned by the smoke pipe. In the cold outdoors, the cooling water passes through the smoke box first, which can prevent the cooling water from freezing and becoming unusable.
[0006] Preferably, the protective pipe is fixedly connected to the outer wall of the smoke exhaust box. The protective pipe includes multiple arc-shaped pipes that match the shape of the smoke exhaust box. The arc-shaped pipes are sleeved on the smoke exhaust box and arranged along the length of the smoke exhaust box. Adjacent arc-shaped pipes are connected by bends.
[0007] With the above structural design, the protective pipe is placed on the outside of the smoke exhaust box, which not only removes heat from the smoke exhaust box, but also serves as heat insulation; it also increases the contact area between the protective pipe and the smoke exhaust box.
[0008] Preferably, a rubber strip is fitted over the outside of the arc-shaped tube.
[0009] The above structural design uses rubber strips to reinforce the connection between the protective pipe and the smoke exhaust box.
[0010] Preferably, the protective pipe is fixedly connected to the inner wall of the smoke exhaust box, and the protective pipe is spiral-shaped.
[0011] The above structural design allows for the removal of more heat.
[0012] Preferably, a plurality of equally spaced partitions are fixedly connected to the outer wall of the smoke exhaust box, and a protective net is fixedly connected to the partitions.
[0013] With the above structural design, a protective net is used to protect the staff. Even if the staff accidentally touches the smoke exhaust box, they will be isolated by the protective net to avoid burns.
[0014] Preferably, the partition is made of a thermally insulating material.
[0015] The above structural design further isolates heat and prevents heat from the exhaust box from being transferred to the protective net.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1) This device has a protective pipe installed on the smoke exhaust box. While supplying water to the water pump, the protective pipe carries away some of the heat from the smoke exhaust box, reducing its temperature. At the same time, the protective pipe is installed on the smoke exhaust box to provide insulation and prevent workers from being accidentally burned by the smoke exhaust pipe.
[0018] 2) When working outdoors in cold weather, it can raise the temperature of the cooling water, which has the advantages of preventing freezing at low temperatures, ensuring smooth pipeline flow, and improving work efficiency. Attached Figure Description

[0020] Figure 2 This is a schematic diagram of the structure of Embodiment 1 of the present utility model;
[0021] Figure 3 This is a schematic diagram of the structure of Embodiment 2 of the present invention;
[0022] Figure 4 This utility model Figure 3 A schematic diagram of the structure from the front view; Detailed Implementation
[0023] Example 1:
[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model provides a technical solution: a gasoline engine-type core drill that prevents burns, including a frame 1, a gasoline engine 2 fixedly connected to the frame 1, and a water pump 3 fixedly connected to the frame 1. When the core drill is drilling, the water pump 3 provides cooling water to the core drill. The gasoline engine 2 includes an exhaust box 21 fixedly connected to the frame 1. A protective pipe 4 is fixedly connected to the wall of the exhaust box 21. The first end of the protective pipe 4 is fixedly connected to a water inlet pipe 5, and the last end of the protective pipe 4 is fixedly connected to a water outlet pipe 6. The water outlet pipe 6 is connected to the water pump 3.
[0025] When a gasoline engine is running, the exhaust gas produced is discharged through the exhaust box 21, causing the temperature of the exhaust box 21 to become too high, posing a risk of burns to workers. When this device is working, the water inlet pipe 5 is connected to a water source, and the cooling water drawn by the water pump 3 passes through the exhaust box 21, carrying away some of the heat from the exhaust box 21. The continuous flow of fresh water through the exhaust box 21 prevents the temperature of the box wall from becoming too high, thus preventing burns to workers. The cooling water only passes through the exhaust box 21 briefly, and the temperature does not rise too much, so it does not affect the use of the core drilling machine. Moreover, when working outdoors in cold weather, the temperature of the cooling water can be raised after passing through the protective pipe 4, preventing the cooling water from freezing at low temperatures during use and ensuring unobstructed pipeline flow.
[0026] The protective pipe 4 is fixedly connected to the outer wall of the smoke exhaust box 21. The protective pipe 4 includes a plurality of arc-shaped pipes 41 that match the shape of the smoke exhaust box 21. The arc-shaped pipes 41 are sleeved on the smoke exhaust box 21 and are arranged along the length of the smoke exhaust box 21. Adjacent arc-shaped pipes 41 are connected by bends 42.
[0027] The arc-shaped tube 41 is fitted with a rubber strip 43. Multiple sets of rubber strips 43 are provided to stably connect the protective tube 4 to the smoke exhaust box 21.
[0028] Working principle: The water inlet pipe 5 is connected to the water source. The cooling water drawn by the water pump 3 passes through the smoke exhaust box 21, carrying away some of the heat from the smoke exhaust box 21. The fresh water continuously passes through the smoke exhaust box 21, thus preventing the temperature of the box wall of the smoke exhaust box 21 from getting too high. Moreover, the protective pipe 4 can prevent the staff from directly contacting the smoke exhaust box 21, thereby preventing the staff from being burned. The cooling water only passes through the smoke exhaust box 21 for a short time, and the temperature will not rise too much, so it will not affect the use of the core drilling machine. In addition, when working in cold outdoor conditions, the temperature of the cooling water can be raised after passing through the protective pipe 4, preventing the cooling water from freezing at low temperatures during use and ensuring that the pipeline is unobstructed.
[0029] Example 2:
[0030] like Figure 3 , Figure 4As shown, Embodiment 2 differs from Embodiment 1 in that the protective pipe 4 is fixedly connected to the inner wall of the exhaust box 21, and the protective pipe 4 is spiral-shaped. The protective pipe 4, located inside the exhaust box 21, can more effectively reduce the temperature on the wall of the exhaust box 21.
[0031] Multiple equally spaced partitions 22 are fixedly connected to the outer wall of the smoke exhaust box 21, and a protective net 23 is fixedly connected to the partitions 22.
[0032] The partition 22 is made of thermal insulation material. The partition 22 is a heat insulation board, which is made of asbestos board, rock wool board or other heat insulation materials.
[0033] Other locations follow the same procedure as in Example 1.
[0034] When using this device, the inlet pipe 5 is connected to a water source. The cooling water drawn by the water pump 3 passes through the exhaust box 21, carrying away some of the heat from the exhaust box 21. The continuous flow of fresh water through the exhaust box 21 prevents the temperature of the box wall from becoming too high. Furthermore, the protective net 23 prevents workers from directly contacting the exhaust box 21, thus avoiding burns. The cooling water only passes through the exhaust box 21 briefly, and its temperature does not rise too much, so it does not affect the use of the core drilling machine. Moreover, when working outdoors in cold weather, the temperature of the cooling water can be raised after passing through the protective pipe 4, preventing the cooling water from freezing at low temperatures during use and ensuring unobstructed pipeline flow.
