Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to an emergency stop device for concrete production. Background Technology

[0002] Concrete is an artificial stone material made by mixing cementitious materials, aggregates, water, and other admixtures in appropriate proportions, followed by mixing, molding, and curing. It is widely used in construction, bridges, roads, and other engineering fields. The concrete production process involves multiple stages, including raw material transportation, mixing, and finished product transportation. Equipment typically includes belt conveyors, mixers, batching machines, and elevators. Production sites present environmental hazards such as dust and noise, and personnel need to operate or maintain equipment at close range. Emergency stop devices are crucial safety measures to prevent personnel from coming into contact with dangerous moving parts. In modern industrial production, concrete, as a basic building material, is of paramount importance in terms of the efficiency and safety of its production process. Concrete production lines encompass multiple stages, including raw material transportation, mixing, and finished product transportation, involving various large-scale mechanical equipment such as belt conveyors, mixers, and batching machines. These devices operate at high speeds and under heavy loads; malfunctions or operational errors can easily lead to serious accidents such as equipment damage, material leaks, and even personal injury. Therefore, emergency stop devices, as critical facilities for ensuring production safety, have extremely high requirements for their reliability, response speed, and applicability.

[0003] Existing emergency stop devices for concrete production have poor protection against emergency stop switches, and accidental activation of the emergency stop switch can easily disrupt operations. Furthermore, existing emergency stop devices for concrete production have poor stability during installation of the emergency stop switch. The present invention provides an emergency stop device for concrete production that solves the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: an emergency stop device for concrete production, including a base plate 1 and a protective cover 2. A U-shaped cavity frame 3 and an emergency stop switch 4 are respectively installed on the front of the base plate 1. Positioning sliders 5 are installed on both sides of the protective cover 2. A positioning block 6 is installed on the top of the protective cover 2. A limit spring 7 is installed inside the U-shaped cavity frame 3. A limit block 8 is installed at one end of the limit spring 7. A push block 9 is installed on the top of the limit block 8. A T-shaped slider 10 is installed at the bottom of the limit block 8. A handle 11 and a connecting rod 12 are respectively installed on the front of the protective cover 2. A baffle 13 is installed at the end of the connecting rod 12 away from the protective cover 2. A threaded hole and a wire hole are respectively opened inside the base plate 1. A bolt 14 is installed inside the threaded hole.

[0025] Specifically, the protective cover 2 and the U-shaped cavity frame 3 serve to protect the emergency stop switch 4, while the positioning slider 5 serves as a guide to facilitate the stability of the movement of the protective cover 2.

[0026] Please see Figures 1 to 3 The protective cover 2 is located inside the U-shaped cavity frame 3. The inner wall of the U-shaped cavity frame 3 is provided with a positioning groove with the left and right direction as the depth direction and the up and down direction as the length direction. The end of the positioning slider 5 is located inside the positioning groove, and the positioning slider 5 can slide along the length direction of the positioning groove.

[0027] Specifically, the wiring hole facilitates wiring, and the protective cover 2 and U-shaped cavity frame 3 enhance the protection of the emergency stop switch 4, preventing accidental contact with the emergency stop switch 4.

[0028] Please see Figures 2 to 5 The wire hole is located inside the U-shaped cavity frame 3, and the emergency stop switch 4 is located in the cavity formed between the U-shaped cavity frame 3 and the protective cover 2. The back of the protective cover 2 abuts against the base plate 1.

[0029] Specifically, the positioning block 6 serves a positioning function, facilitating the closure of the protective cover 2 and the U-shaped cavity frame 3.

[0030] Please see Figures 3 to 4 The inner top wall of the U-shaped cavity frame 3 is provided with a positioning groove with the depth direction as the vertical direction, and the end of the positioning block 6 is inserted into the inside of the positioning groove.

[0031] Specifically, the T-shaped slider 10 serves as a positioning guide, improving the stability of the movement of the limit block 8 and facilitating the limit block 8 to restrict the position of the positioning block 6.

[0032] Please see Figures 3 to 4 The U-shaped cavity frame 3 has a T-shaped groove inside, with the vertical direction as the depth direction and the horizontal direction as the length direction. The end of the T-shaped slider 10 is located inside the T-shaped groove, and the T-shaped slider 10 can slide along the length direction of the T-shaped groove.

[0033] Specifically, the setting of the limit block 8 facilitates the restriction of the position of the positioning block 6, thereby improving the stability of the closure between the protective cover 2 and the U-shaped cavity frame 3.

[0034] Please see Figures 3 to 4 The positioning block 6 has a limiting groove on one side with the left and right direction as the depth direction, and the end of the limiting block 8 away from the limiting spring 7 is inserted into the inside of the limiting groove.

[0035] In use, when installing the emergency stop device, push the push block 9 to move the limit block 8 and the T-shaped slider 10, causing the T-shaped slider 10 to slide along the length of the T-shaped groove. This causes the limit spring 7 to contract, displacing the end of the limit block 8 from the limit groove. Then, move the protective cover 2 downwards using the handle 11, causing the positioning slider 5 to slide along the length of the positioning groove. This facilitates exposing the emergency stop switch 4 inside the U-shaped cavity frame 3 and the protective cover 2. The connecting rod 12 and the baffle 13 move with the protective cover 2, moving the baffle 13 away from the threaded hole. Insert the bolt 14 into the threaded hole, and then tighten the bolt 14 to easily install the base plate 1 in the appropriate position. Finally, use the handle 11 to... 1. Move the protective cover 2 upwards, so that the positioning slider 5 slides along the length of the positioning groove, and the end of the positioning block 6 is inserted into the interior of the positioning groove. When the positioning block 6 is fully inserted into the interior of the positioning groove, the limiting groove and the limiting block 8 are aligned. Release the push block 9, and through the elastic tension of the limiting spring 7, the end of the limiting block 8 is inserted into the interior of the limiting groove, which facilitates the restriction of the position of the positioning block 6, facilitates the closing of the protective cover 2, facilitates the protection of the emergency stop switch 4, and avoids accidental contact with the emergency stop switch 4. At this time, the baffle 13 abuts against the bolt 14, and the position of the bolt 14 is restricted by the baffle 13 to prevent the bolt 14 from loosening and falling off, thereby improving the stability of the emergency stop device installation and improving its practicality.
