Description

Technical Field

[0001] This utility model relates to the field of roasting furnace installation technology, specifically to a tool for installing a roasting furnace top component. Background Technology

[0002] Currently, during the construction of carbon roasting furnace projects, the installation of components at the top of the heating flue is carried out using steel wire ropes secured with rope slings. Installation workers hold the steel wire rope slings to hoist the components to the top of the heating flue, and after fixing and adjusting them, they use one hand to hold the upper end of the steel wire rope sling and the other hand to use a tool to detach the sling from the components. This installation method poses a significant safety hazard.

[0003] (1) During the process of crane hoisting the components, the wire rope sleeve is soft and the weight of the components is more than 200Kg. The swing amplitude is large during the operation of the crane, which causes the gripping of the wire rope sleeve to be unstable, which can easily cause injury to the installation personnel.

[0004] (2) During the removal of the wire rope sleeve, it is unavoidable that the installation workers will come into contact with the wire rope sleeve. If the crane is lifting too fast and the installation workers do not withdraw their grip on the wire rope in time, it is easy to cause hand injuries.

[0005] Therefore, it is necessary to design an installation tool for the furnace top components of the roasting furnace to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an installation tool for the top components of a roasting furnace, so as to solve the problem of significant safety hazards associated with hoisting components with steel wire ropes as mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tool for installing components on the top of a roasting furnace, comprising a first boom, a first crossarm fixedly installed at the top of the first boom and movably connected to an external hook, a second crossarm extending through the lower part of the first boom, first clamping arms movably connected to both ends of the second crossarm, a second clamping arm movably connected between the outer side of the first clamping arm and the second crossarm, the first clamping arm and the second clamping arm being arranged crosswise, a stop block fixedly connected between the outer side of the second clamping arm and the second crossarm, a first connecting rod fixedly connected between the first clamping arm and the second clamping arm, and contact detection components respectively provided at the ends of the first clamping arm and the second clamping arm away from the first boom.

The width of the straight slots is greater than the diameter of the annular groove and less than the diameter of the center of the second cross arm. The diameter of the stop block is greater than the width of the straight slots. The first and second clamping arms have gripping openings at their ends away from the first boom. A third cross arm is rotatably connected to the inside of the first and second clamping arms near the gripping openings. The third cross arm is welded to the first connecting rod.

[0010] Preferably, the contact detection assembly includes a support plate that is bolted to the top of the first and second clamping arms near the gripping opening. Mounting holes are respectively provided on both sides of the first and second clamping arms inside the support plate. A metal proximity switch is threaded into the mounting holes. A battery is fixedly connected to the top surface of the support plate on one side of the metal proximity switch. The battery is electrically connected to the metal proximity switch. A protective shell is provided on the outside of the battery and the metal proximity switch. A contact portion is provided at the bottom of the support plate, and the probe of the metal proximity switch extends into the contact portion.

[0011] Preferably, the contact part includes a sleeve fixedly connected to the support plate. The inner diameter of the sleeve is the same as the diameter of the mounting hole.

An "L"-shaped plate that contacts the workpiece is provided at the end of the telescopic arm away from the spring.

[0012] Preferably, a signal receiver is provided on one side of the first boom, and a signal light is electrically connected above the signal receiver.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) By setting up a first boom, a first cross boom, a second cross boom, a first clamping arm and a second clamping arm, the first cross boom is connected to an external hook, the two ends of the second cross boom are movably connected to the first clamping arm and the two are cross-set with the second clamping arm, and the multi-degree-of-freedom movement is achieved in conjunction with the annular groove and the straight groove, so that the workpiece can be stably clamped during hoisting, reducing the risk of injury to the installer due to the large swing amplitude caused by the use of wire rope to hoist the workpiece;

[0015] (2) Through the cooperation of the support plate, metal proximity switch, battery, protective shell and contact part in the contact detection assembly, after the "L" shaped plate of the contact part contacts the workpiece, the metal sensing plate is driven by the spring and the second connecting rod to approach the metal proximity switch to collect the signal. Then the signal receiver and the signal light cooperate to display the clamping status, ensuring that the clamping is in place every time, avoiding the situation where the clamping is insufficient in some areas and the subsequent lifting to the top of the furnace is carried out, further ensuring the safe construction of the installation workers.

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1-5An installation tool for a roasting furnace top component includes a first boom 1. A first crossarm 2, which is movably connected to an external hook, is fixedly installed at the top of the first boom 1. A second crossarm 3 is installed through the lower part of the first boom 1. First clamping arms 4 are movably connected to both ends of the second crossarm 3. A second clamping arm 5 is movably connected between the outer side of the first clamping arm 4 and the second crossarm 3. Annular grooves 31, which can accommodate the thickness of the first clamping arm 4 and the second clamping arm 5, are respectively opened at both ends of the second crossarm 3. The first clamping arm 4 and the second clamping arm 5 are arranged crosswise. The second crossarm 3 is welded to the first boom 1. A stop block 6 is fixedly connected between the outer side of the second clamping arm 5 and the second crossarm 3. When the first boom 1 is lifted by the external hook, the first clamping arm 4 and the second clamping arm 5 can rotate along the annular groove 31, achieving one degree of freedom.

[0024] The first clamping arm 4 and the second clamping arm 5 have straight slots 41 at their ends near the first boom 1. The sidewall of the straight slot 41 is slidably connected to the outer wall of the annular groove 31. The width of the straight slot 41 is greater than the diameter of the annular groove 31 and less than the diameter of the center of the second cross arm 3. The diameter of the stop block 6 is greater than the width of the straight slot 41. A first connecting rod 7 is fixedly connected between the first clamping arm 4 and the second clamping arm 5. A clamping opening 42 is provided at the end of the first clamping arm 4 and the second clamping arm 5 away from the first boom 1. A third cross arm 43 is rotatably connected to the side of the first clamping arm 4 and the second clamping arm 5 near the clamping opening 42. The third cross arm 43 is welded to the first connecting rod 7. Through the setting of the straight slot 41 and the sliding connection with the annular groove 31, the first clamping arm 4 and the second clamping arm 5 can slide close to the annular groove 31, realizing another degree of freedom.

[0025] During the rotation and sliding of the first clamping arm 4 and the second clamping arm 5 around the second cross arm 3, the intersection angle of the upper ends of the first clamping arm 4 and the second clamping arm 5 can change. After the third cross arm 43 and the connecting rod form a fulcrum, the lower ends of the entire first clamping arm 4 and the second clamping arm 5 can rotate inward around the fulcrum, so as to achieve close clamping of the workpiece to be installed.

[0026] Contact detection components 8 are respectively provided at the ends of the first clamping arm 4 and the second clamping arm 5 away from the first boom 1. The contact detection components 8 include a support plate 81 which is fixedly connected to the top of the first clamping arm 4 and the second clamping arm 5 near the gripping opening 42 by bolts. The support plate 81 has mounting holes on both sides of the first clamping arm 4 and the second clamping arm 5. A metal proximity switch 82 is threaded into the mounting holes. A battery 83 is fixedly connected to the top surface of the support plate 81 on one side of the metal proximity switch 82. The battery 83 is electrically connected to the metal proximity switch 82. A protective shell 84 is provided on the outside of the battery 83 and the metal proximity switch 82. A top cover is hinged to the protective shell 84. A contact part 85 is provided at the bottom of the support plate 81. The probe of the metal proximity switch 82 extends into the contact part 85.

[0027] Specifically, the contact part 85 includes a sleeve 851 fixedly connected to the support plate 81. The inner diameter of the sleeve 851 is the same as the diameter of the mounting hole. A fixing plate 852 is provided inside the sleeve 851. A through hole is opened in the middle of the fixing plate 852. A second connecting rod 853 is slidably arranged inside the through hole. One end of the second connecting rod 853 is located between the fixing plate 852 and the metal proximity switch 82, and a metal sensing plate 854 is fixedly arranged thereon. A telescopic arm 857 is provided at the other end of the second connecting rod 853. The telescopic arm 857 is slidably connected to the sleeve 851. A spring 855 is provided between the fixing plate 852 on the outside of the second connecting rod 853 and the telescopic arm 857. The telescopic arm 857 is located away from the fixing plate 852 on the outside of the second connecting rod 853 and the telescopic arm 857. One end of the spring 855 is provided with an "L"-shaped plate 856 that contacts the workpiece. When the workpiece is in place, after entering the clamping port 42, it will contact the "L"-shaped plate 856. The telescopic arm 857 retracts into the sleeve 851, compressing the spring 855 to overcome its elasticity. Through the second connecting rod 853, the metal sensing plate 854 is pushed close to the metal proximity switch 82. After reaching the detection distance of the metal proximity switch 82, the signal is collected and then transmitted to determine whether all four clamping ports 42 have achieved effective clamping contact with the workpiece. This avoids the possibility that the clamping ports 42 may not be in place, resulting in a loss of clamping effect and causing the workpiece to fall and injure the installation worker.

[0028] Furthermore, in order to enable installation workers to promptly perceive whether all four gripping ports 42 are in contact with the workpiece, a signal receiver 9 is installed on one side of the first boom 1. An indicator light 10 is electrically connected above the signal receiver 9. The contact status between the workpiece and the four gripping ports 42 is determined by whether the indicator light 10 is lit.

[0029] Working principle: When using this utility model, the hook is connected to the first horizontal arm 2 of the first boom 1. After moving it above the workpiece, it continues to move downwards towards the workpiece, placing the clamping ports 42 on both sides of the workpiece. The first boom 1 is pulled upwards, and the lower ends of the first clamping arm 4 and the second clamping arm 5 move towards the workpiece. After contacting the workpiece, the workpiece presses down the "L"-shaped plate 856 and the telescopic arm 857 into the sleeve 851, so that the metal sensing plate 854 approaches the metal proximity switch 82. After the workpiece is clamped in place, the metal proximity switch 82 detects the signal and sends it to the signal receiver 9, which controls the indicator light 10 to light up. One light is used to provide feedback on the clamping status of the clamping port 42 at the end of the first clamping arm 4, and the other light is used to provide feedback on the clamping status of the second clamping arm 5. When both lights are lit, the installer can determine that the workpiece is clamped in place and can continue to pull the hook until it is fully lifted.
