Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of belt compression device, more particularly to an electric portable transmission belt compression device. BACKGROUND

[0002] In the process of ship design and construction, there are often devices driven by the propeller main engine pulley, such as engine-driven cabin bottom fire pump, engine-driven rudder oil pump, engine-driven generator, etc. Generally, such engine-driven devices do not need to run all the time, but only need to be combined and discharged under certain working conditions (combining and discharging is to compress the belt 300, so that the driving pulley 400 drives the driven pulley 500 through the tensioned belt 300, and then the driven pulley 500 drives the corresponding equipment to work). For example, the main engine drives the fire pump, which is usually in a discharging state (discharging is that the belt 300 is in a loose state, the driving pulley 400 cannot drive the driven pulley 500 to rotate through the loose belt 300, and then the driven pulley 500 cannot drive the corresponding equipment to work), and only when the fire needs to be put out, the fire pump needs to be combined and discharged to work. At this time, a simple and quick device is needed to quickly combine and discharge the fire pump.

[0003] At present, the commonly used way is Figure 1 、 Figure 2 The belt compression device shown in the figure needs to loosen the nut 100 when it needs to be combined and discharged, manually lift the tensioner 200, make the tensioner 200 contact with the belt and tighten the belt, and then lock the nut 100. However, this operation needs to loosen and tighten the nut 100 with a wrench, which takes a long time and is complicated and inconvenient. Moreover, since the tensioner 200 needs to be manually lifted, the personnel are close to the belt and the pulley, which has a certain operation risk.

[0004] Therefore, how to provide an electric portable transmission belt compression device that is simple, quick and safe to operate and can compress the belt is a problem that technicians in the field need to solve urgently. UTILITY MODEL CONTENTS

[0005] Therefore, the utility model provides an electric portable transmission belt compression device that is simple, quick and safe to operate and can compress the belt.

[0041] 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.

[0042] like Figures 3-6 As shown, this utility model embodiment discloses an electric portable transmission belt tightening device, comprising:

[0043] Adjustable base 1, the adjustable base 1 is provided with a vertical adjustment hole 101 for adjusting its height, and the connecting bolt passes through the vertical adjustment hole 101 to fix the adjustable base 1 to a fixed body (such as the base of a ship's hull);

[0044] Electric telescopic rod 2, the housing of electric telescopic rod 2 is fixedly connected to adjustable base 1;

[0045] The belt tensioning assembly 3 is connected to the telescopic end of the electric telescopic rod 2.

[0046] In a specific embodiment, the belt tensioning assembly 3 includes:

[0047] T-shaped plate 31, the horizontal plate 311 of T-shaped plate 31 and the telescopic end of electric telescopic rod 2 can be detached and connected by bolts;

[0048] Connecting shaft 32, one end of which is detachably connected to the vertical plate 312 of T-shaped plate 31;

[0049] The belt tensioning cylinder 33 is sleeved on the connecting shaft 32.

[0050] A first bearing 4 and a second bearing 5 are spaced apart on the connecting shaft 32, and a belt tensioning cylinder 33 is fixed on the outer ring of the first bearing 4 and the second bearing 5.

[0051] The belt tensioning cylinder 33 has a first bearing mounting groove 331 and a second bearing mounting groove 332 at both ends. The first bearing 4 is embedded in the first bearing mounting groove 331 and the second bearing 5 is embedded in the second bearing mounting groove 332.

[0052] The first bearing 4 is axially limited on one side of the bottom surface of the first bearing mounting groove 331. One end of the connecting shaft 32 has a stop head 321, and the other side of the second bearing 5 is axially limited on one side of the stop head 321. The second bearing 5 is axially limited on one side of the bottom surface of the second bearing mounting groove 332, and the other end of the connecting shaft 32 is fitted with a stop plate 6. The other side of the second bearing 5 is axially limited on one side of the stop plate 6.

[0053] The other end of the connecting shaft 32 passes through the vertical plate 312 and is locked to the other side of the stop plate 6 by the locking nut 7 screwed onto the connecting shaft 32.

[0054] A friction pad 8 is pressed between the locking nut 7 and the vertical plate 312, and the friction pad 8 is sleeved on the connecting shaft 32.

[0055] The driving pulley 400 drives the driven pulley 500 to rotate together via the belt 300. Because the belt 300 is slightly longer than the required length, the driven pulley 500 will not rotate when no external force is applied due to insufficient friction.

[0056] When the driven pulley 500 needs to work, press the clamping device down to gradually tighten the belt 300. Due to the increase in friction, the driven pulley 500 will start to rotate driven by the driving pulley 400 through the belt 300. Press down further to ensure that the belt 300 does not slip.

[0057] The specific steps are as follows:

[0058] When belt tensioning is required, the electric telescopic rod is remotely controlled from the control console to move downwards. The electric telescopic rod moves the belt tensioning cylinder downwards, thereby tightening the belt and putting it in a taut state. At this time, the driving pulley can drive the driven pulley to rotate through the tensioned belt, and the driven pulley can then drive other equipment to operate. When belt tensioning is not required, the electric telescopic rod moves the belt tensioning cylinder upwards and disengages from the belt, putting the belt in a slack state. At this time, the driving pulley cannot drive the driven pulley to rotate through the belt, and the driven pulley stops rotating.

[0059] The advantages of this clamping device are as follows:

[0060] 1. Compact and small structure, low cost.

[0061] 2. Easy to install; only a base needs to be made at the shipyard, and the device can be connected with bolts.

[0062] 3. Easy to operate. Simply press a button on the control panel to control the electric telescopic rod to achieve the purpose of tightening or loosening the belt.

[0063] 4. During the clamping process, the drive pulley can be in a running state or a stopped state.

[0064] 5. High safety; the operation process is far from the pulley, eliminating the risk of injury.

[0065] 6. Durable: The belt tensioner has a built-in bearing, which can avoid the problem of excessive friction during high-speed rotation, thus preventing the belt tensioner from overheating.

[0066] 7. All parts can be replaced at any time.

[0067] 8. The distance between the belt tensioner and the belt is small, which ensures that the belt will not come off the belt groove of the pulley.

[0068] It should be noted that this device can be installed above the belt, such as... Figure 3 As shown, the belt is tensioned by lowering the belt tensioning cylinder. Alternatively, the device can be placed below the belt; when not in use, the belt tensioning cylinder is lowered to slack the belt. When in use, the belt tensioning cylinder is raised to tension the belt.

[0069] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
