Description

Technical Field

[0001] The utility model belongs to the technical field of sintering machine trolley in the iron and steel metallurgy industry, and particularly relates to a device for fastening bolts of trolley baffles. Background Art

[0002] As is well known, the sintering machine trolley is one of the main production equipments in the metallurgy industry. The trolley baffle is an important part of the sintering machine trolley. During the daily production process, the problem of the trolley baffle becoming loose often occurs. In order to ensure the safe and normal use of the trolley, it is often necessary to tighten the bolts of the trolley baffle online during production operation. During the process of tightening the bolts of the trolley baffle, since the nut and the screw often rotate simultaneously, it requires two people to cooperate in the operation at the same time, and the safety cannot be reliably guaranteed during the operation, and the operation efficiency is low. Therefore, considering the improvement of the safety factor of the operators and the operation efficiency, it has become an urgent problem to safely and efficiently tighten the bolts of the trolley baffle.

[0003] As is well known, the sintering machine trolley occupies an important position in the metallurgy industry and is one of the key equipments in the whole production process. The trolley baffle, as the core component of the sintering machine trolley, plays a crucial role. During the daily production process, we often encounter the problem that the trolley baffle becomes loose. If this problem is not solved in time, it will affect the normal progress of production. Therefore, in order to ensure the safe and stable operation of the trolley, in the actual production process, it is often necessary to tighten the bolts of the trolley baffle online.

[0004] However, during the actual process of tightening the bolts of the trolley baffle, engineers found a very thorny problem, that is, the nut and the screw often rotate simultaneously. This problem makes the tightening work complicated and requires two people to cooperate in the operation at the same time, which increases the operation difficulty to a certain extent. Moreover, during the operation process, the safety problem cannot be effectively guaranteed, and coupled with the low operation efficiency, these have made the tightening work of the bolts of the trolley baffle an urgent problem to be solved.

[0005] Therefore, in order to improve the safety factor of the operators and the operation efficiency, it is necessary to find a safer and more efficient method for tightening the bolts of the trolley baffle. This is not only the maintenance and improvement of the production equipment in the metallurgy industry, but also a protection for the operators and an optimization of the production process. It is necessary to solve this problem through technological innovation so as to improve the overall level of China's metallurgy industry. Content of the Utility Model

[0027] In order to make the above objects and advantages of the present utility model clearer, the following embodiments are used to further elaborate on the present utility model in detail. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] As Figures 1-6 shown:

[0029] A device for fastening the bolts of the trolley baffle, which includes a series of carefully designed components that work together to achieve convenient and effective fastening of the trolley baffle bolts. It mainly includes the following parts:

[0030] First is the adjusting bolt 1. The main function of this component is to adjust the height of the entire device to ensure its applicability in different working environments. The adjusting bolt is uniquely designed with its threaded rod vertically upward, which makes the operation more convenient.

[0031] Next is the adjusting sleeve 2. A plurality of pin holes 3 are evenly arranged on the side wall of this component. These pin holes are designed to cooperate with the use of the pin 6 to fix the position of the adjusting sleeve and prevent it from rotating during the process of tightening the nut.

[0032] The hexagon socket 4 is a component used to fix the nut at the lower end of the trolley baffle. Its design takes into account the matching with the trolley baffle nut and the cooperation with the adjusting sleeve to ensure the overall tightening effect.

[0033] The internal thread sleeve 7 is a component used in conjunction with the adjusting bolt 1. Its size is the same as that of the adjusting bolt, and its length is between 40 - 60 mm. This can ensure that while adjusting the bolt, the internal thread sleeve can also be firmly fixed at the lower end of the adjusting sleeve.

[0034] The pin 6 is a component used to fix the adjusting sleeve 2. It is inserted into the pin hole to prevent the adjusting sleeve from rotating during the process of tightening the nut. The design of the pin is also carefully considered. The length of the left pin is greater than that of the right pin, which can prevent the device from rotating synchronously when tightening the upper nut. The pin is inserted into the pin hole to fix the adjusting sleeve, and the length of the left pin is greater than that of the right pin to prevent the device from rotating synchronously when tightening the upper nut.

[0035] When working, a wrench 5 is also needed. This component is used to fix the nut above the trolley baffle. Its handle can be stuck at the vertical rib of the trolley baffle, which can better fix the wrench and improve the tightening efficiency. The wrench is used separately from the above device. The length of the handle is greater than the distance from the trolley baffle bolt to the right vertical rib of the trolley baffle. When tightening the nut below the trolley baffle, the handle of the wrench can be firmly fixed and fitted with the vertical rib of the trolley baffle.

[0036] Based on the above embodiments, the following optimized technical features can be further adopted: The size of the adjusting bolt can use bolts with a diameter of 24 mm or 25 mm. It is appropriate that the bottom of the bolt can be placed on the width of the cross rib plate of the trolley baffle. The length is selected between 40 mm and 60 mm. The selected diameter size of the adjusting sleeve is between 45 mm and 55 mm. The pin holes on the side wall are evenly distributed up and down and left and right. The diameter of the pin hole is between 16 mm and 20 mm, and the distance between adjacent pin holes is between 30 mm and 50 mm. The internal hexagonal sleeve is cut and made of an iron plate with a thickness of 15 - 16 mm. The model size of the internal hexagon is the same as that of the nut of the trolley baffle. The outer diameter size of the internal hexagon is the same as the diameter size of the adjusting sleeve. It is welded and fixed at the upper end of the adjusting sleeve. The size of the internal thread sleeve is the same as that of the adjusting bolt, and the length is selected between 40 and 60 mm. It is welded and fixed at the lower end of the adjusting sleeve.

[0037] Working principle:

[0038] When tightening the upper nut, first align the adjusting sleeve with the lower nut of the trolley baffle, then adjust the adjusting bolt at the lower end of the adjusting sleeve to the cross rib plate of the trolley baffle. Use a monkey wrench to make the lower end of the bolt fit tightly with the cross rib plate of the trolley baffle. Select an appropriate pin hole and insert the pin. The protruding length of the left pin is greater than that of the right pin. Then use a monkey wrench to tighten the nut above the trolley baffle.

[0039] When tightening the lower nut, first fix the wrench on the nut above the trolley baffle, select a suitable position to make the wrench handle fit tightly with the right vertical rib of the trolley baffle, and then use a monkey wrench to tighten the nut below the trolley baffle.

[0040] Through such a design and working principle, this device can achieve rapid, accurate and stable tightening of the bolts of the trolley baffle, greatly improving work efficiency and at the same time reducing labor intensity.

[0041] The above description is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
