In view of the above, the present inventors have devised a gutter cover fixing device. And a fixing pile is arranged on one side of the cable trench, and the position of the fixing pile corresponds to the position of a trench cover plate positioned at the end part of the cable trench. The compression piece is rotatably arranged on the fixed pile, and can be propped against the groove cover plates positioned at the end parts of the cable trench by rotating the compression piece, so that a plurality of groove cover plates on the cable trench are prevented from being blown off from the end parts in sequence in the windy weather.

One end of the pressing member 120 is rotatably mounted on the fixing pile 110, and the other end of the pressing member 120 is configured to abut against the top surface of the cover plate.

The distance between the fixing pile 110 and the cover plate can be set according to the size of the compressing element 120, so that the other end of the compressing element 120 can be propped against the top surface of the cover plate. The length of the fixing piles 110 may be set according to the distance between the top surface of the cover plate and the ground, which is not limited only. It should be noted that, when the plurality of cover plates on the cable trench are arranged along the length direction of the cable trench, the fixing piles 110 and the cover plates at the ends are arranged along the width direction of the cable trench, so that the cover plate fixing device does not obstruct the cover plates to be arranged on the cable trench.

In one possible embodiment, the number of the cover plate holders can be two, by means of which two cover plates of the plurality of cover plates on the cable trench are respectively held at both ends

It will be appreciated that the hold-down 120 can rotate about the axis of the spud 110, and that the axial direction of the spud 110 is perpendicular to the gland plate to ensure that the hold-down 120 does not interfere with the gland plate during rotation, and that a worker can rotate the hold-down 120 on the spud 110 to hold down the gland plate or reverse rotate the hold-down 120 on the spud 110 to disengage the other end of the hold-down 120 from the gland plate.

The trench cover fixing device provided by the embodiment of the utility model comprises a trench cover fixing mechanism 100, wherein the trench cover fixing mechanism 100 comprises a fixing pile 110 and a pressing piece 120. The fixing pile 110 is fixedly installed on one side of the cable pit, and the position of the fixing pile 110 corresponds to the position of the groove cover plate positioned at the end part of the cable pit. One end of the pressing member 120 is rotatably mounted on the fixing pile 110, and the other end of the pressing member 120 is configured to abut against the top surface of the cover plate. After a plurality of ditch cover plates are covered on the cable duct in proper order, can make the other end of compressing tightly 120 offset with the top surface of the ditch cover plate that is located the tip through rotating compressing tightly 120, compress tightly the ditch cover plate that is located the tip through compressing tightly 120, when meetting the windy weather, ensure that a plurality of ditch cover plates can not be blown in proper order from the tip and lift, guarantee the life of ditch cover plate. When the operator needs to open the cover plate, the cover plate can be opened by only reversely rotating the pressing member 120 on the fixing pile 110.

In addition, the stable cover of the ditch cover plate can be ensured to be arranged on the cable ditch through the ditch cover plate fixing device, so that the small animals can be prevented from entering the interior of the cable ditch to damage the cable in the cable ditch.

In one embodiment, as shown in FIGS. 1-4, the cover plate securing mechanism 100 further includes two stop members 130. The two limiting members 130 are installed on the fixing piles 110 at intervals, the compressing members 120 are located between the two limiting members 130, and each limiting member 130 abuts against the compressing member 120.

It will be appreciated that the spacing between the two stop members 130 is at the same height as the portion of the hold-down member 120 located on the stake 110. Fig. 2 shows that the bottom end of the upper limiting member 130 abuts against the top surface of the pressing member 120, and the top end of the lower limiting member 130 abuts against the bottom surface of the pressing member 120, i.e., the pressing member 120 is clamped between the two limiting members 130.

For example, stoppers may be used as the stoppers 130, and each stopper may be fixed to the fixing piles 110 by welding.

By installing two limiting pieces 130 on the fixing pile 110, the pressing piece 120 is clamped by the two limiting pieces 130, so that the pressing piece 120 is prevented from moving along the axial direction of the fixing pile 110, and the pressing piece 120 is ensured to be capable of reliably pressing a trench cover plate on a cable trench.

In one embodiment, as shown in fig. 1-4, the top of the spud 110 is provided with a threaded section 111. The limiting member 130 is a nut, the nut is sleeved on the threaded section 111 and is in threaded connection with the threaded section 111, and the compressing member 120 is clamped between the two nuts.

In one possible implementation, as shown in fig. 2 and 3, the fixing pile 110 includes a polish rod section 112 and a screw thread section 111 located on top of the polish rod section 112, and the polish rod section 112 is disposed coaxially with the screw thread section 111. Wherein, an iron rod with the length of 500mm and the diameter of 20mm can be used as the polish rod section 112, and a screw rod can be welded on the iron rod as the thread section 111. In one possible implementation, a fixing bolt may be welded to the top of the polished rod segment 112, and the top of the polished rod segment 112 is connected to the head of the fixing bolt, and the screw of the fixing bolt is used as the threaded segment 111 of the fixing pile 110. Schematically, the head of the fixing bolt can also play a limiting role on the nut. It should be noted that, before the fixing device for the gutter cover is used, it is necessary to check whether the polish rod section 112 and the threaded section 111 are welded well or not, so as to ensure that the fixing pile 110 can be used stably and reliably.

In other embodiments, an iron bar may be used as the spud 110, and threads may be provided on top of the iron bar by turning to form the threaded section 111 on top of the spud 110.

It will be appreciated that after the nut is placed over the threaded section 111, the height of the nut on the threaded section 111 can be adjusted by rotating the nut, i.e., the cover plate securing mechanism 100 can properly adjust the height of the nut and the compression member 120 between the two nuts to accommodate different terrain.

According to the structure, the height of the pressing piece 120 on the fixed pile 110 can be adjusted by rotating the nut, so that the pressing piece 120 can press the cover plates with different heights, and the universality of the cover plate fixing device is improved. When the other end of the pressing member 120 abuts against the top surface of the cover plate, the pressing force of the pressing member 120 on the cover plate can be adjusted by rotating the nut, thereby reliably pressing the cover plate. In addition, the clamping force of the two nuts to the pressing piece 120 can be adjusted by rotating the nuts, and the pressing piece 120 can be prevented from being separated from the cover plate after the other end of the pressing piece 120 abuts against the top surface of the cover plate.

In a particular embodiment, the length of the thread segments 111 is greater than or equal to 100mm. That is, the length of the thread segments 111 is not less than 100mm.

Through the arrangement, the height adjusting range of the compressing piece 120 can be ensured, so that the compressing piece 120 can compress the cover plates with different heights, and the universality of the cover plate fixing device is further ensured.

In one embodiment, as shown in fig. 5, the stop 130 is a sleeve 131. The sleeve 131 is sleeved on the fixed pile 110 and is in sliding connection with the fixed pile 110. The cover plate fixing mechanism 100 further comprises two fasteners 140, the two fasteners 140 penetrate through the two sleeves 131 in a one-to-one correspondence, and the end portions of the fasteners 140 are propped against the fixing piles 110.

It will be appreciated that the sleeve 131 is capable of sliding along the axial direction of the fixing pile 110 after being sleeved on the fixing pile 110. Illustratively, an adjusting bolt may be used as the fastener 140, and accordingly, the side wall of each sleeve 131 is provided with a threaded hole communicating with the inside of the sleeve 131, and the screw of the adjusting bolt extends into the threaded hole and is screwed with the threaded hole. Wherein, adjusting bolt's tip stretches into the inside of sleeve 131, can make adjusting bolt follow the axial motion of screw hole through rotatory adjusting bolt. When the position of the sleeve 131 needs to be adjusted, the fastener 140 is rotated so that the end part of the fastener 140 is separated from the fixing pile 110, and the sleeve 131 can be slid; after the sleeve 131 slides to the preset position, the fastener 140 is rotated reversely to make the end of the fastener 140 prop against the fixing pile 110, so that the sleeve 131 can be locked on the fixing pile 110.

According to the structure, the heights of the sleeves 131 on the fixing piles 110 are adjusted, so that the pressing pieces 120 can press the cover plates with different heights, the pressing force applied to the cover plates by the pressing pieces 120 can be adjusted, in addition, the two sleeves 131 can clamp the pressing pieces 120, and when the other ends of the pressing pieces 120 are propped against the top surfaces of the cover plates, the pressing pieces 120 can be prevented from being separated from the cover plates.

As shown in fig. 1-5, in one embodiment, the compression member 120 is a platen. One end of the pressing plate is provided with a through hole, the fixing piles 110 penetrate through the through hole, and each limiting piece 130 is respectively propped against the position of the pressing plate at the edge of the through hole.

The shape of the pressing plate may be a rectangle or an ellipse, for example, as shown in fig. 4, the shape of the pressing plate may be a rectangle, and the length of the rectangle may be 100mm and the width may be 50mm. The pressure plate can be made of metal materials so as to ensure the structural strength of the pressure plate. The through hole is close to the other end of the pressing plate, and the axis of the through hole extends along the thickness direction of the pressing plate, wherein the size of the through hole is matched with the size of the fixing pile 110.

In this structure, the pressing plate is used as the pressing member 120, and when the other end of the pressing member 120 abuts against the top surface of the cover plate, the pressing plate is tightly attached to the top surface of the cover plate, so that the pressing member 120 can reliably press the cover plate.

In other embodiments, a compression bar may be used as the compression member 120, one end of which may be rotatably mounted to the fixing pile 110 by a bearing, and the other end of which may be abutted against the top surface of the gutter cover.

Further, the thickness of the pressing plate is 1.5mm-2.5mm.

It should be noted that, when the thickness of the pressing plate is less than 1.5mm, it is difficult to ensure the structural strength of the pressing plate, that is, under the windy weather, the cover plate may drive the pressing plate to bend under the action of wind force. When the thickness of the pressing plate is greater than 2.5mm, the pressing plate protrudes from the cover plate, and the height of the pressing plate is high, so that the pressing plate can influence workers to walk on the cover plate.

The structure does not influence the staff to walk on the ditch cover plate on the basis of ensuring the structure strength of the pressing plate.

In one embodiment, as shown in fig. 6 and 7, one side of the cable trench is provided with a pre-buried foundation 150. The bottom end of the fixed pile 110 stretches into the embedded foundation 150, and the fixed pile 110 and the embedded foundation 150 are fixed through pouring.

The depth of the pre-buried foundation 150 may be 300mm, and after the bottom end of the fixing pile 110 extends into the pre-buried foundation 150, concrete 200 may be poured into the pre-buried foundation 150, and the fixing pile 110 and the pre-buried foundation 150 are fixed by the concrete 200. The cross-sectional dimension of the embedded foundation 150 is not limited in this embodiment, and may be set by those skilled in the art according to actual needs.

Through the above-mentioned setting can be with stake 110 fixed mounting in one side of cable pit, and the reliability of stake 110 is higher, and during windy weather, stake 110 is difficult to take place to empty.

Further, as shown in fig. 7, a portion of the fixing pile 110 extending into the pre-buried foundation 150 is provided with a limit rod 113, and after casting, the concrete 200 is coated on the limit rod 113. The above arrangement can further improve the stability of the fixing pile 110, and ensure that the fixing pile 110 does not topple over in windy weather.

In one embodiment, the cover plate securing device includes two cover plate securing mechanisms 100, the two cover plate securing mechanisms 100 being disposed on opposite sides of the cover plate, respectively.

For example, the two cover plate fixing mechanisms 100 may be symmetrically disposed at two opposite sides of the cover plate, and the pre-buried bases 150 may be disposed at two opposite sides of the cover plate, and the bottom ends of the fixing piles 110 of the two cover plate fixing mechanisms 100 extend into the two pre-buried bases 150 in a one-to-one correspondence. It will be appreciated that two cover plate securing mechanisms 100 can secure both sides of the cover plate top surface.

Through the arrangement, the reliability of the fixing device of the cover plate on the cover plate can be further improved, so that the cover plate has higher wind resistance.
