Description

Technical Field

[0001] The utility model relates to the field of tunnel lining trolleys, in particular to a walking mechanism of a trolley component. Background Art

[0002] In tunnel construction, trolleys are common equipment, which are used to assist workers in lining tunnels. Needle-beam trolleys are common trolleys. When the formwork components or frames on the needle-beam trolleys are moved, they are generally driven by a winch or hoist, or driven by a cylinder. However, when the moving parts are driven by a winch or hoist (electric or manual hoist), the requirements for anchor points and pull ropes are high. If the anchor point is unstable or the pull rope is not strong enough, the breakage of the pull rope or the flying of the anchor rod will bring greater safety hazards to the workers. When driven directly by a cylinder, the stroke of the cylinder is required to be high, which is not suitable for long-distance movement. Utility Model Content

[0003] Therefore, in order to solve the above-mentioned deficiencies, the utility model provides a traveling mechanism suitable for a tunnel lining trolley, which can realize the travel of the moving part driven by the traveling cylinder and the moving component with a locking tongue, and the position of the moving component can be moved by the extension and retraction of the cylinder, which is convenient for walking. The locking tongue can control whether the moving part and the track are locked (the locking means that the moving component and the track do not move relative to each other) so as to form a fulcrum and realize the travel of the moving part or the moving component.

[0004] Specifically, a traveling mechanism of a trolley component includes a traveling cylinder and a track, wherein both ends of the traveling cylinder are respectively connected to a moving component installed on the track; the moving component has a locking tongue adapted to and rotatable with the track (the rotation of the locking tongue is used to control whether the moving component and the track are locked, and the locking means that the moving component and the track do not move relative to each other).

[0005] Optionally, the moving assembly further comprises a locking frame and a locking cylinder;

[0006] The track runs through the locking frame;

[0007] The middle part of the locking tongue is hinged to the locking frame, one end of the locking tongue has a locking portion adapted to the upper surface of the track, and the other end is hinged to one end of the locking cylinder;

[0008] The other end of the locking oil cylinder is hinged to the locking frame.

[0009] Optionally, a lower locking block is provided at the gap between the lower surface of the track and the locking frame, and the lower locking block is fixedly connected to the locking frame. A locking portion adapted to the lower portion of the track is provided at the upper end of the lower locking block, and a gap is provided between the locking portion of the lower locking block and the track, and the size of the gap changes as the locking frame moves up and down.

[0010] Optionally, the locking portion is formed by a plurality of protruding teeth.

[0011] Optionally, the track is fixed to the first traveling member, wherein the locking frame at one end is connected to the second traveling member via a connecting seat, and the connecting seat is hinged to the locking frame;

[0012] The first traveling member and the second traveling member move relatively under the action of the trolley traveling mechanism.

[0013] The utility model has the following advantages:

[0014] The utility model uses the extension and retraction of the travel cylinder as a driving force to drive two moving components (such as a needle beam and a frame that travels on the needle beam) to send relative movement. The moving component with a locking tongue can provide a fulcrum for the travel cylinder, and the position of the travel cylinder can also be changed by the moving component, thereby changing the moving position of the driven component (such as the above-mentioned frame) to achieve a change in the driving distance of the travel mechanism; the driven component can be moved over a long distance, and the long distance can be the extension and retraction stroke of multiple travel cylinders.

[0021] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0022] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0023] As described in the background technology, in tunnel construction, trolleys are common equipment, which are used to assist workers in lining the tunnel; the needle-beam trolley is a common trolley, and the template assembly or frame on the needle-beam trolley is generally driven by a winch or hoist when moving, or driven by a cylinder; however, when the moving parts are driven by a winch or hoist (electric or manual hoist), the requirements for anchor points and pull ropes are high. If the anchor point is unstable or the pull rope is not strong enough, the breakage of the pull rope or the flying of the anchor rod will bring greater safety hazards to the workers; and when directly driven by a cylinder, the stroke requirements for the cylinder are high, which is not suitable for long-distance movement.

[0024] Based on the above reasons, Figure 1 and Figure 2 As shown, this embodiment provides a walking mechanism of a trolley component, including a walking cylinder 100 and a track 300, and a moving component 200 installed on the track is respectively connected to both ends of the walking cylinder 100; the moving component has a locking tongue 203 adapted to and rotatable with the track 300 (the rotation of the locking tongue is used to control whether the moving component and the track are locked, and the locking means that the moving component and the track do not move relative to each other).

[0025] The above technical features can realize the driving of the trolley assembly (for example, a frame installed on the needle beam, which needs to walk on the needle beam), improve the walking stability of the driven assembly, and use the oil cylinder as a power source to achieve a larger driving force and improve the operation effect. In addition, the left and right sides of the driving oil cylinder are provided with moving assemblies with a locking function (locking is achieved through a rotatable locking tongue), which can realize the change of the position of the oil cylinder, and the moving distance of the driven assembly can be better changed through the change of the position.

[0026] In order to achieve the movement and locking of the moving assembly, in one embodiment, the moving assembly further includes a locking frame 201 and a locking cylinder 202;

[0027] The track 300 passes through the locking frame;

[0028] The middle part of the locking tongue 203 is hinged to the locking frame 201, one end of the locking tongue 203 has a locking portion adapted to the upper surface of the track, and the other end is hinged to one end of the locking cylinder 202;

[0029] The other end of the locking cylinder is hinged to the locking frame 201 .

[0030] Furthermore, in order to improve the locking ability and to better provide a reliable support point for the traveling oil cylinder, a lower locking block 204 is provided at the gap between the lower surface of the track and the locking frame. The lower locking block 204 is fixedly connected to the locking frame 201, and a locking portion adapted to the lower part of the track is provided at the upper end of the lower locking block 204. There is a gap between the locking portion of the lower locking block and the track, and the size of the gap changes with the up and down movement of the locking frame. Preferably, in order to make the locking ability stronger after the track contacts the locking tongue, the locking portion is formed by a plurality of convex teeth. When in use, when the locking portion of the locking tongue 203 contacts the track, the lower locking block is lifted upward, the locking portion of the lower locking block contacts the track, and the track is clamped to the upper and lower locking portions; after the upper locking portion is disengaged from the track, the lower locking portion is also disengaged from the track, releasing the clamping force of the upper and lower locking portions on the track.

[0031] For example, Figure 1 As shown, the track is fixed to the first walking member 400 (e.g., a needle beam), wherein a locking frame at one end is connected to the second walking member 500 (e.g., a frame that walks on the needle beam) via a connecting seat 205, and the connecting seat is hinged to the locking frame; the first walking member and the second walking member move relative to each other under the action of the trolley walking mechanism.

[0032] The above technical features use the form of a shaped oil cylinder pushing or pulling to drive the second walking member (such as a frame walking on the needle beam) to continuously walk on the first walking member (such as the needle beam). By driving the frame to move in this way, the stability and reliability of the frame when moving can be ensured, and a greater driving force is provided for the dragging of the template group; in the above technical features, when the frame moves, such as Figure 3As shown in the figure, the moving component away from the frame end is locked (that is, the moving component and the track remain fixed and do not move relative to each other), and the moving component connected to the frame end is in an unlocked state (that is, the moving component and the track can move relative to each other), and then the travel cylinder is controlled to extend the telescopic rod to drive the frame to move on the needle beam by ejection; when a travel cylinder stroke is completed, the moving component away from the frame end is unlocked, and the moving component connected to the frame end is locked (as shown in the figure). Figure 4 As shown in the figure, the travel cylinder is retracted, and the moving component is dragged away from the frame end to move (as shown in the figure). Figure 5 As shown); when you need to continue moving the frame, repeat the above steps.

[0033] In the above technical features, the locking principle of the moving component is: the telescopic movement of the locking cylinder drives the locking tongue to rotate. When the locking part of the locking tongue contacts the track, the locking cylinder continues to drive. At this time, the locking frame is lifted up (that is, the gap between the lower surface of the track and the lower locking block is reduced). The track is clamped between the locking tongue and the lower locking block, and the locking is completed by the upper and lower locking parts (that is, the moving component and the track remain fixed and no relative movement occurs).

[0034] The unlocking principle of the moving component is: after the moving component is in a locked state, the locking cylinder telescopes in the opposite direction to drive the locking tongue to disengage from the track. After the locking tongue is disengaged from the track, the gap between the lower locking block and the track increases until they are separated, thereby achieving unlocking of the moving component and the track (i.e., the moving component and the track can have relative movement).

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
