For some trench covers that need to bear weight, they are required to have a large span and strong load-bearing capacity. The size and weight of the cover will also increase accordingly, which leads to the need to use lifting equipment to assist in the process of opening and closing the cover. In order to meet the load requirements, the ordinary hooks used on the lifting equipment are generally large in size, and when connected to the lifting point, the tip of the hook needs to pass through the hole of the lifting point, and then the lifting point is hung on the bottom of the hook. Therefore, the construction space required for this ordinary hook is relatively large, which also requires the groove depth, width and other dimensions at the hidden lifting point to be larger, resulting in poor surface passability of the cover and safety risks. Utility Model Content

[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0039] Embodiment 1
[0040] like Figure 1 As shown, it is a preferred embodiment of the hook of the utility model. This hook is suitable for connecting the hidden lifting points on the groove cover plate and the lifting equipment. Since this hook is small in size and the connection method with the lifting point 4 is different from that of the ordinary hook, the required construction space is small, and the corresponding requirements for the depth and width dimensions of the groove at the lifting point 4 are also relatively small.
[0041] The hook comprises: a connecting ring 1, a lifting ring 2 and a sliding member 3. The upper part of the connecting ring 1 is connected to the lifting equipment, the lower part of the connecting ring 1 is connected to the lifting ring 2, and the lifting ring 2 is connected to the lifting point 4 set in the groove of the cover plate 5. The bottom end of the lifting ring 2 has a notch, and channels 201 are set on both sides of the notch. The sliding member 3 is slidably set in the channel 201, and the length of the sliding member 3 is greater than the length of the notch, so that the sliding member 3 can open or close the notch when sliding. When the notch is opened, the lifting ring 2 can be moved to the lifting point 4, and then the sliding member 3 is slid, so that one end of the sliding member 3 passes through the lifting hole on the lifting point 4 and then slides into the channel 201 on the other side. At this time, the two ends of the sliding member 3 are respectively located in the two channels 201, and the connection between the lifting ring 2 and the lifting point 4 is completed, and the notch is closed, and the groove cover plate 5 can be directly lifted by the lifting equipment. When it is necessary to separate the lifting ring 2 and the lifting point 4, the sliding member 3 can be slid to open the notch and separate the lifting point 4 from the lifting ring 2. When this type of hook is in use, unlike an ordinary hook, it is not necessary to pass the tip through the hanging hole of the hanging point 4 to complete the connection with the hanging point 4, but it is directly connected by passing the sliding member 3 through the hanging hole. Therefore, this type of hook requires a relatively small construction space, and accordingly, the depth and width requirements of the groove at the hanging point 4 are relatively small, so that the cover plate 5 has better passability and can also improve the safety of passing pedestrians and vehicles.
[0042] Further, such as Figure 2 As shown, the connecting ring 1 includes: an upper ring 101, a lower ring 102 and a connecting piece 103. The upper ring 101 and the lower ring 102 are both approximately U-shaped, and the connecting piece 103 is approximately H-shaped. The two ends of the connecting piece 103 are connected to the upper ring 101 and the lower ring 102 respectively. The upper ring 101 is connected to the lifting equipment, and the lower ring 102 is connected to the lifting ring 2. And the outer edge size of the upper ring 101 is larger than the outer edge size of the lower ring 102, from Figure 2It can also be seen that the two sides of the connecting piece 103 connecting the corresponding ends of the upper ring 101 and the lower ring 102 are inclined due to the different sizes of the upper ring 101 and the lower ring 102. This is because the upper ring 101 is connected to the lifting equipment, and the hook on the general lifting equipment is relatively large, and the large-sized upper ring 101 is easy to match and connect with the hook. The lower ring 102 is connected to the lifting ring 2 and close to the hidden lifting point 4, and the small-sized lower ring 102 will not increase the construction space of the lifting ring 2.
[0043] like Figure 3 As shown, the shape of the lifting ring 2 is approximately a circular ring, with a notch at the bottom. A baffle 203 is also provided inside the lifting ring 2, and the baffle 203 divides the lifting ring 2 into two parts, the lower ring 102 of the connecting ring 1 is connected to the upper part of the lifting ring 2. The baffle 203 can also increase the structural strength of the lifting ring 2 and improve the load-bearing capacity of the hook.
[0044] Furthermore, the upper part of the lifting ring 2 has a slide groove 202, the shape of which matches the shape of the sliding member 3, and the two ends of the slide groove 202 are respectively connected to the two channels 201, that is, the sliding member 3 can slide in the channel 201 as well as in the slide groove 202.
[0045] The channel 201 is an arc-shaped hollow channel 201 formed on the lifting ring 2, and the extending direction of the channel 201 is arc-shaped along the direction of the outer edge of the lifting ring 2. The arc-shaped hollow channel 201 matches the shape of the sliding member 3, and its cross section is circular. When the sliding member 3 slides in the channel 201, the lifting ring 2 can limit the radial displacement of the sliding member 3, so that the sliding member 3 performs a circular motion around the center of the lifting ring 2.
[0046] Further, the sliding member 3 includes: a sliding part 301 and an operating part 302. The shape of the sliding part 301 matches the arc hollow channel 201, and the sliding part 301 is slidably arranged in the channel 201 and the chute 202. The sliding of the sliding part 301 can open or close the gap of the hanging ring 2. The operating part 302 is a round rod, one end of the operating part 302 is connected to the sliding part 301, and the operating part 302 is arranged along the radial direction of the hanging ring 2. The sliding part 301 is driven to slide by controlling the operating part 302. The setting of the operating part 302 is more convenient for manipulating the sliding part 301. Since the operating part 302 is arranged along the radial direction of the hanging ring 2, it cannot enter the channel 201, and the chute 202 arranged on the upper part of the hanging ring 2 is the activity space left for the operating part 302. The sliding of the operating part 302 along the chute 202 can control the sliding part 301 to slide in the chute 202 and the channel 201.
[0047] like Figure 4 , Figure 5As shown, the sliding member 3 also includes a locking mechanism arranged at the connection between the sliding part 301 and the operating part 302. Specifically, the locking mechanism includes: a locking block 303 and a screw rod 304. The screw rod 304 is also arranged along the radial direction of the lifting ring 2. One end of the screw rod 304 is connected to one end of the sliding part 301, and the other end is threadedly connected to the operating part 302. The locking block 303 is arranged on the screw rod 304, and the bottom surface of the locking block 303 is in contact with the top surface of the slide groove 202. When it is necessary to lock the position of the sliding part 301, tighten the operating part 302 so that the locking block 303 is in close contact with the slide groove 202. A large friction force is generated between the two, which can limit the further movement of the sliding part 301, thereby achieving the purpose of locking, so as to ensure the safety of the subsequent lifting of the cover plate. When the sliding part 301 needs to move, just loosen the operating part 302.
[0048] In other embodiments, the locking mechanism may not be provided. After the sliding portion 301 passes through the lifting point 4, the cover plate 5 is directly lifted by the lifting equipment. During the lifting process, the gravity of the cover plate 5 is applied to the sliding portion 301, so that the friction between the sliding portion 301 and the side wall of the channel 201 is increased, and the sliding portion 301 is prevented from continuing to slide in the channel 201.
[0049] In other embodiments, the locking mechanism may also be other structures. For example, a plurality of holes may be arranged at intervals on both sides of the slide groove 202, and through holes may be arranged on both sides of the operating part 302 facing the slide groove 202. When the operating part 302 is moved into place, the through holes of the operating part 302 are aligned with the holes on the side of the slide groove 202, and then pins are inserted for limiting.
[0050] The following is a description of the use of the hook provided in this embodiment:
[0051] First, connect the lifting ring 2 and the lifting point 4. Specifically, move the lifting ring 2 to the lifting point 4, open the gap of the lifting ring 2, and then control the operating part 302 to drive the sliding part 301 to slide, and one end of the sliding part 301 passes through the lifting hole on the lifting point 4 and then slides into the channel 201 on the other side to complete the connection with the lifting point 4.
[0052] Afterwards, tighten the operating part 302, and lock it by friction between the locking block 303 and the chute 202, so that the sliding member 3 can no longer slide. Then, connect the hook of the lifting device to the upper ring 101 of the connecting ring 1, and the groove cover plate 5 can be lifted by the lifting device.
[0053] When removing the cover plate 5, first loosen the operating part 302, then separate the sliding part 301 from the hanging point 4 and open the gap of the hanging ring 2, and then the hook can be removed as a whole.
[0054] Embodiment 2
[0055] The difference between this embodiment and the first embodiment is that the channel 201 on the lifting ring 2 has a different structure, and the remaining structures are the same as the structure of the lifting hook in the first embodiment, so they will not be described in detail.
[0056] In this embodiment, the channel 201 is an arc-shaped groove formed on the hanging ring 2, and the sliding part 301 can slide in the arc-shaped groove, and the arc-shaped groove can also limit the radial displacement of the sliding part 301, but the difference is that the operating part 302 can also slide in the arc-shaped groove, that is, the section of the hanging ring 2 where the arc-shaped groove is set will not prevent the operating part 302 from sliding, while the section of the hanging ring 2 in the embodiment 1 where the arc-shaped hollow channel 201 is set will hinder the sliding of the operating part 302. Specifically, the arc-shaped groove can be formed by opening a notch in the outer wall of the channel in the embodiment 1, and the operating part 302 can slide at the notch. The channel 201 with such an arc-shaped groove is conducive to reducing the overall size of the sliding member 3.
[0057] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
